Posted 2023-02-15 Wiiix

有时开启新的app而内存不够时，其它app可能会被Out Of Memory Killer清除防止进程不被杀死的办法:

1.在androidManifest.xml文件中设置persistent属性为true

  <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:persistent="true">

2.在前端运行程序

    private void startForeground() 
        Notification notification = new NotificationCompat.Builder(this)
                .setContentTitle(getResources().getString(R.string.app_name))
                .setTicker(getResources().getString(R.string.app_name))
                .setContentText("Running")
                .setSmallIcon(R.drawable.unlock)
                .setContentIntent(null)
                .setOngoing(true)
                .build();
        startForeground(9999,notification);
