The previous compilation of the APK results in either deleting all APKs in the app/build and app/release directories, or deleting all files in both directories and then compiling the APK.

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

general app has a demand to hide the Android default Title bar, is usually used before setConvertView call requestWindowFeature (Window. FEATURE_NO_TITLE), after can sometimes find call this line of code has no effect, Very depressed.
through observation, before the Activity is to inherit the Activity, so is valid, and I am AppCompatActivity inherited, so can’t hide.
solution:
1. Let xxxActivity inherit the Activity
2. Inherit AppCompatActivity and call it in the onCreate method

if (getSupportActionBar() != null){
   getSupportActionBar().hide();
}

And then we’re done.

public class TitlebarActivity extends AppCompatActivity

In Android Studio, activities inherit from AppCompatActivity by default, so the requestWindowFeature(window.feature_no_title) method fails.

There are two solutions

> change AppCompatActivity to Activity, then requestWindowFeature(window.feature_no_title); Add the following code to the onCreate() method:

if (getSupportActionBar() != null){
   getSupportActionBar().hide();
}

Now you can hide the title bar.

The Intent solution cannot be updated in the onRestart method
Override the change method in the Activity

protected void onNewIntent(Intent intent) {  
       super.onNewIntent(intent);  
       // must store the new intent unless getIntent() will return the old one  
       setIntent(intent);  
       }
