Android 广播接收器上的引导/屏幕不工作

我有一个空白的HelloWorld应用程序：

package tutorials.TestReceivers;

import android.app.Activity;
import android.os.Bundle;

public class TestReceiversActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

使用此BootReceiver.Java：

package tutorials.TestReceivers;

import android.content.BroadcastReceiver;

public class BootReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent arg1) {
    Intent intent = new Intent(context, TestReceiversActivity.class);
        context.startActivity(intent);    
    }
}

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

这份清单：

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

在运行应用程序并关闭它之后

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

当我解锁屏幕（屏幕打开）时，什么都没有发生

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

当我启动decive时，我会收到下一条信息，比如：

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

“应用程序TestReceivesActivity（tutorials.TestReceives进程）意外停止。请重试”

删除

android permission=“android.permission.RECEIVE\u BOOT\u COMPLETED”

。将此权限的

元素添加为

元素的子元素

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

如果问题仍然存在，请使用Eclipse中的adb logcat、DDMS或DDMS透视图查看logcat并检查与崩溃相关的堆栈跟踪

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

显示如何在引导时获得控制

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

屏幕上的

无法从清单中工作。

经过长时间的挫折，我解决了上面的问题

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

注册引导广播接收器（并根据它打开活动）的正确方法是：

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

空白HelloWorld应用程序（TestReceiversActivity.java）：

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

另一个引导接收器类（BootReceiver.java）

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

注意：必须设置标志才能使其工作

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

将清单设置为：

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestReceiversActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver
            android-permission="android.permission.RECEIVE_BOOT_COMPLETED"
            android:name="development.TestReceiversActivity.BootReceiver" >
            <intent-filter >
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.SCREEN_ON" />
            </intent-filter>
        </receiver>
    </application>
