앱이 실행되면 권한창을 띄워주고, 권한을 허가하지 않으면 앱 종료 코드.

public class MainActivity extends AppCompatActivity {

    String[] permission_list = {
            Manifest.permission.INTERNET,
            Manifest.permission.RECORD_AUDIO,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE
    };
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        checkPermission();
    }
 
    
    public void checkPermission(){
        //현재 안드로이드 버전이 6.0미만이면 메서드를 종료한다.
        //안드로이드6.0 (마시멜로) 이후 버전부터 유저 권한설정 필요
        if(Build.VERSION.SDK_INT < Build.VERSION_CODES.M)
            return;
 
        for(String permission : permission_list){
            //권한 허용 여부를 확인한다.
            int chk = checkCallingOrSelfPermission(permission);
 
            if(chk == PackageManager.PERMISSION_DENIED){
                //권한 허용을여부를 확인하는 창을 띄운다
                requestPermissions(permission_list,0);
            }
        }
    }
    
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(requestCode==0)
        {
            for(int i=0; i<grantResults.length; i++)
            {
                //허용됬다면
                if(grantResults[i]==PackageManager.PERMISSION_GRANTED){
                }
                else {
                    //권한을 하나라도 허용하지 않는다면 앱 종료
                    Toast.makeText(getApplicationContext(),"앱권한설정하세요",Toast.LENGTH_LONG).show();
                    finish();
                }
            }
        }
    }
