I arrive on a white screen when I try to switch activities on my android app

Question

I just want to switch activity with a simple button

Button test = findViewById(R.id.please);

    test.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            Log.d("MainActivity","I pass there ");
            Intent intent = new Intent(MainActivity.this, TestActivity.class);
            startActivity(intent);
            Log.d("MainActivity","I pass there too");
        }
    });

I don't have an error, I just arrive on a white screen and not on my new activity. Logs appear in my console. I also have a log when I create my second activity but this one doesn't appear.

for more code, This is my manifest :

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".HomeActivity">

    </activity>
    <activity android:name=".ScheduleActivity"></activity>
    <activity android:name=".MapActivity"></activity>
    <activity android:name=".TestActivity"
              android:theme="@style/YourTheme">

    </activity>
</application>

TestActivity :

    public class TestActivity extends AppCompatActivity {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState, @Nullable PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(R.layout.activity_test);

        Log.d("TestActivity","I arrived in Test Activity !!");
    }
} 

the button in activity_main :

</android.support.design.widget.AppBarLayout>
<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="wtf"
    android:background="@color/colorAccent"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:id="@+id/please"
    />

Activity_test :

<?xml version="1.0" encoding="utf-8"?>

<ImageView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_map_black_24dp"/>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="hello there! :D"/>

Answer 1

You are Overriding wrong onCreate method in TestActivity. You have to override this method:

protected void onCreate(@Nullable Bundle savedInstanceState) {}
