Android PiP模式和应用程序生命周期

我正在将画中画模式添加到我的应用程序,发现生命周期存在问题。官方文档说:“当您的活动切换到PIP时,系统会将活动置于暂停状态并调用该活动的onPause()方法。视频播放不应暂停,并且如果在PIP模式下暂停该活动,则视频播放应该继续播放。 ”但就我而言,进入画中画模式后,我的命令如下:

07-19 17:03:40.094 Enter PiP mode
07-19 17:03:40.193 OnPause(
07-19 17:03:40.780 OnStop()
07-19 17:03:40.788 OnDestroy()
07-19 17:03:40.927 OnCreate()
07-19 17:03:40.937 OnStart()
07-19 17:03:41.014 OnResume
07-19 17:03:41.024 OnPause()

怎么了?之后,我会在一个小的PiP窗口中重新启动应用程序。

public void Pip_Click(View v) {

        if (android.os.Build.VERSION.SDK_INT >= 26) {
            //Trigger PiP mode
            try {
                Rational rational = new Rational(simpleExoPlayerView.getWidth(), simpleExoPlayerView.getHeight());

                PictureInPictureParams mParams = new PictureInPictureParams.Builder()
                                .setAspectRatio(rational)
                                .build();

                appendLog("enter PiP mode");
                enterPictureInPictureMode(mParams);

                setFullScreen();
            } catch (IllegalStateException e) {
                e.printStackTrace();
            }
        } else {
            Toast.makeText(MainActivity.this, "Not supported", Toast.LENGTH_SHORT).show();
        }

    }

来自清单:

<activity
            android:name=".MainActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:supportsPictureInPicture="true"
            android:label="@string/app_name"
            android:launchMode="singleTask">

        </activity>

通过更改此方法解决了我的问题:

<activity
            android:name=".MainActivity"
            android:resizeableActivity="true"
            android:configChanges="orientation|keyboardHidden|screenSize|smallestScreenSize|screenLayout"
            android:supportsPictureInPicture="true"
            android:label="@string/app_name"
            android:launchMode="singleTask">
        </activity>
