Java – Android Power Manager Wake Lock

androidandroid-wake-lockjavapower-managementwakelock

I've got application which is playing TV streams and needs to be ON all the time.
I do acquire wake lock in OnCreate()

pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, TAG);
wl.acquire();

and then release in onDestroy()

if (wl != null) {
    wl.release();
    wl = null;
}

User usually minimize the app by pressing back, home or power button
and then resumes from home screen tapping the app icon.
I do release wake lock in onPause() and acquire in onResume().

Time to time I see application crashes or disappears completely from screen and I see
logs related to wake lock.

Is this a best practice to control Android Power Manager Wake Lock?

Any opinions are welcome.

As you are saying that you do release wake lock in onPause() and acquire in onResume(). That is a good practice however alongwith these I suggest you to release wakelock in onUserLeaveHint() as well.

onUserLeaveHint()

@Override
protected void onUserLeaveHint() {

try {
     // your code.

     // release the wake lock
     wl.release();

    }catch(Exception ex){
     Log.e("Exception in onUserLeaveHint", ex.getMessage);
    }
    super.onUserLeaveHint();
}

Android – How to close/hide the Android soft keyboard programmatically

You can force Android to hide the virtual keyboard using the InputMethodManager, calling hideSoftInputFromWindow, passing in the token of the window containing your focused view.

// Check if no view has focus:
View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

This will force the keyboard to be hidden in all situations. In some cases, you will want to pass in InputMethodManager.HIDE_IMPLICIT_ONLY as the second parameter to ensure you only hide the keyboard when the user didn't explicitly force it to appear (by holding down the menu).

Note: If you want to do this in Kotlin, use: context?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

Kotlin Syntax

// Only runs if there is a view that is currently focused
this.currentFocus?.let { view ->
    val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
    imm?.hideSoftInputFromWindow(view.windowToken, 0)
}

Android – How to stop EditText from gaining focus at Activity startup in Android

Excellent answers from Luc and Mark. However, a good code sample is missing. Adding the tags android:focusableInTouchMode="true" and android:focusable="true" to the parent layout (e.g. LinearLayout or ConstraintLayout) like in the following example, will fix the problem.

<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
    android:focusable="true" 
    android:focusableInTouchMode="true"
    android:layout_width="0px" 
    android:layout_height="0px"/>

<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/autotext"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:nextFocusUp="@id/autotext" 
    android:nextFocusLeft="@id/autotext"/>
