Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE

Question

I am making Notification app and struggling with below error:

java.lang.IllegalArgumentException: com.tonyapp.rabbitfarm: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I searched the solutions for this issue and there are no solution work for me.

below is my Mainactivity.java code:

 btnCancel.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            NotifyMe.cancel(getApplicationContext(),"test");
        }
    });


    btnNotify.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dpd.show(getSupportFragmentManager(),"DatePickerDialog");
        }
    });
}

@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {

    now.set(Calendar.YEAR,year);
    now.set(Calendar.MONTH,monthOfYear);
    now.set(Calendar.DAY_OF_MONTH,dayOfMonth);

    tpd.show(getSupportFragmentManager(),"timepicker");



}

@Override
public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {


    now.set(Calendar.HOUR_OF_DAY,hourOfDay);
    now.set(Calendar.MINUTE,minute);
    now.set(Calendar.SECOND,second);



    NotifyMe notifyMe = new NotifyMe.Builder(getApplicationContext())
            .title(edt1.getText().toString())
            .content(edt2.getText().toString())
            .color(255,0,0,255)
            .led_color(255,255,255,255)
            .time(now)
            .addAction(new Intent(),"Snooze",false)
            .addAction(new Intent(),"Dismiss",true)
            .addAction(new Intent(),"Done")
            .large_icon(R.mipmap.ic_launcher_round)
            .build();

}

Please help me fix this problem. thanks in advance.

Answer 1

1. Determine whether your project has pending intent.
2. If Yes then search for PendingIntent in the whole project and add the flag to PendingIntent like this.

• before

PendingIntent mPendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);

• after

PendingIntent mPendingIntent = PendingIntent.getActivity(mContext, 0, intent, PendingIntent.FLAG_MUTABLE);

OR

If there is no PendingIntent in your project or you get an error even though you write the flag:

• Add the following to your build.gradle(app) dependencies.

dependencies {
  // For Java
  implementation 'androidx.work:work-runtime:2.7.1' 

  // For Kotlin
  implementation 'androidx.work:work-runtime-ktx:2.7.1'
}
