我正在为Android开发一个应用程序。 该应用程序使用Google Play服务，需要一些许可

launcher活动非常简单，只需设置内容视图。 我正在各种设备上测试它，结果如下：

HOMTOM HT3 PRO，安卓5.1快速显示第一个活动

华为P8 Lite、Android 6.0有时会在启动前显示5-10秒的黑屏

Galaxy A3，Android 6.1它被卡在了黑屏上

Nexus 5卡在黑屏上

我的开始活动

public class StartActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_start);
        //more code
    }

}
但在调试过程中，我清楚地看到等待时间是在onCreate调用之前。这可能取决于应用程序由大量文件组成吗？我有73个java类+100个可绘制类

仅供参考，这是我的gradle文件

您使用什么API来开发您的简单应用程序？你说的“简单应用”是什么意思？你能给我们一个代码片段吗，也许是来自你的Java代码，也许是你的布局文件？你说你需要使用你的应用程序的权限，这些权限是被授予的吗？旧款手机有时不会显示弹出窗口，要求用户提供其所需的权限。你可以在手机应用程序的设置中启用它们。我说了“简单启动活动”，我把它附在了我的帖子上。我现在将尝试检查权限并让您知道。为什么m3View为空？您能否显示布局以及m3View的启动位置？m3View它不是“我的视图”。我认为这是与系统有关的。顺便说一句，我正在不同的设备上做更多的测试，我会尽快让你知道。很抱歉，onCreate方法上还有一些代码表现不好。开始时仍有一些加载时间，但可以通过在主题xml中设置
true
来平滑加载时间。
