Простой крах Android-проекта из-за нарушения режима StrictMode ThreadPolicy, строгого режима. DiskReadViolation

0 голосов
/ 07 октября 2019

Я создал новый проект Android, пустой проект-занятие и использовал StrictMode, но приложение каждый раз вылетает из-за строгого режима.DiskReadViolation

Я отвечаю на мой похожий вопрос, заданный здесь Чтение диска StrictModeнарушение setContentView для пустого действия, где решение запускается мгновенно, но я использую Android studio 3.5.1, а мгновенный запуск заменен на «Применить изменения». 

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        if (BuildConfig.DEBUG) {
            StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                    .detectDiskReads()
                    .detectDiskWrites()
                    .detectNetwork()
                    .penaltyLog()
                    .penaltyDeath()
                    .build());
            StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                    .detectLeakedSqlLiteObjects()
                    .detectLeakedClosableObjects()
                    .penaltyLog()
                    .penaltyDeath()
                    .build());
        }
        super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_main);
    }
}

Это мой logcat, вызванный: android.os.strictmode.DiskReadViolation
