So, my Activity A is :
public class imei extends AppCompatActivity {
//variables
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_imei);
...
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if(Long.parseLong(IMEI) == IMEI2){
IMEI .equals(IMEI2);
textView.setText("IMEI NUMBER : " + IMEI);
Bundle bundle = new Bundle();
bundle.putBoolean("key", true);
Intent intent = new Intent(imei.this, menu_utama.class);
intent.putExtras(bundle);
imei.this.startActivity(intent);
}else{}
now i want to pass value the Boolean value from bundle to Activity B :
public class MyApplication extends Application {
private BeaconManager beaconManager;
//variables
@Override
public void onCreate() {
super.onCreate();
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
final boolean success = bundle.getBoolean("key");
..code
if(success){
do something
}else{do something
but the getIntent()
is red, but when i change to extends AppCompatActivity
, getIntent()
correct. somehow it has to do with onCreate(Bundle savedInstanceState)
and extends Application
what should i do to fix this
so my problem is how to passing value between activity class to aplication class, first try i'm using Bundle which is using getIntent(), but it did not work because getIntent() is in activity class, because i want to using in application class, so i'm using shared Preference and it works.
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("masuk", true);
// Save the changes in SharedPreferences
editor.apply(); // commit changes
put it in activity class and get the shared preferences in application class:
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("masuk", true);
// Save the changes in SharedPreferences
editor.apply(); // commit changes
and then just use if(masuk){do what you want here}else{do what you want here}
Solved.
