Android 与FileProvider共享日志文件失败
我正在尝试使用FileProvider内容提供程序共享我的内部日志文件。我在舱单中有以下条目:Android 与FileProvider共享日志文件失败,android,android-fileprovider,Android,Android Fileprovider,我正在尝试使用FileProvider内容提供程序共享我的内部日志文件。我在舱单中有以下条目: <provider android:name="android.support.v4.content.FileProvider" android:authorities="nl.charm.nedradio" android:exported="false" android:grantUriPermissions="true"> <meta-d
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="nl.charm.nedradio"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_provider_paths" />
</provider>
创建共享意图的代码是:
private static final String LOGFILE_NAME = "log.txt";
private static final String AUTHORITY = "nl.charm.nedradio";
public static Intent getShareIntent(Context context)
{
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "Log File");
intent.putExtra(Intent.EXTRA_TEXT, "App logfile.");
// Allow access outside of share application's realm
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
File logFile = new File(context.getExternalFilesDir(null), LOGFILE_NAME);
Uri logURI = FileProvider.getUriForFile(context, AUTHORITY, logFile);
intent.putExtra(Intent.EXTRA_STREAM, logURI);
return intent;
}
意图的创建工作正常,但当我尝试与Gmail等共享时,logcat中出现以下错误:
2018-10-18 10:16:49.536 4585-4585/com.google.android.gm E/Gmail: Gmail:Error adding attachment
exk: FileNotFoundException when openFileDescriptor.
我一直在寻找答案,但没有找到。有没有关于我做错了什么的建议?经过进一步搜索,我发现我使用了不正确的位置来保存日志文件。为了解决这个问题,我必须对logback.xml配置进行以下更改:
<configuration>
<property name="LOGFILE_NAME" value="log.txt" />
<property name="EXT_FILES_DIR" value="${EXT_DIR:-/sdcard}/Android/data/${PACKAGE_NAME}/files" />
<appender name="rollingfile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${EXT_FILES_DIR}/${LOGFILE_NAME}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>${LOGFILE_NAME}.%i</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>1</maxIndex>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>400KB</maxFileSize>
</triggeringPolicy>
<encoder>
<pattern>%date %-5level %logger{10} - %msg%n</pattern>
</encoder>
</appender>
<root level="TRACE">
<appender-ref ref="rollingfile" />
</root>
</configuration>
现在共享可以与Gmail和Google Drive一起使用。这里有一个类似的问题,我的答案中有一个。请检查,我保证可以解决您的问题
