Question

每当我尝试运行我的应用程序时，我都会收到以下错误：

Unexpected error while executing: am start -n "com.example.amran.myapplication/com.example.amran.myapplication.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while Launching activity

这是MainActivity的代码：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

这是Logcat输出：
