如果应用程序崩溃或ram clear或android os释放应用程序的内存，请重新启动应用程序

Question

如果出现崩溃问题或ram清除或释放内存最终会清除变量并且NPE将会发生，我想重新启动应用程序。

我尝试了Solution 1和Solution 2以及

public class MyApplication extends Application {

    private static final String TAG = MyApplication.class.getName();

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();

        Thread.setDefaultUncaughtExceptionHandler(onRuntimeError);
    }

    /*
     * To handle the crash issues, and restart from the last state.
     */
    private Thread.UncaughtExceptionHandler onRuntimeError = new Thread.UncaughtExceptionHandler() {
        public void uncaughtException(Thread thread, Throwable ex) {
            ex.printStackTrace();
            try {

                Log.e(TAG, "App crash");
                // Try starting the Activity again
                Intent intent = new Intent(getApplicationContext(),
                        SplashScreenActivity.class);
                Toast.makeText(getApplicationContext(), "test",
                        Toast.LENGTH_SHORT).show();
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
                Log.e(TAG, "App crash2");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
}

但是在所有情况下都不会显示应用重启或吐司信息，只会出现白屏并且还会打印日志。

ACRA仅对报告日志有用吗，还是需要额外注意应用程序重启或阻止ANR？
