我在項目中使用了Firebase身份驗證材料。今天我決定將FCM整合到我的項目中。但我無法從我的Firebase控制檯收到任何通知。我也嘗試重新下載.json文件，但沒有成功。你們對我的問題有什麼想法嗎？我的設備未收到Firebase雲消息傳遞通知

The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

我認爲這個問題不是由我的MainActiviy.java決定的，但我會向你展示以防萬一。
MainActivity.java
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener{
private Fragment fragment;
private FragmentManager fragmentManager;
public TextView tarih;
final String PREFS_NAME = "MyPrefsFile";
final String SHAREDPREF_DATE = "SharedPrefDate";
private FirebaseAuth firebaseAuth;
private TextView textViewUserEmail;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
firebaseAuth = FirebaseAuth.getInstance();
if(firebaseAuth.getCurrentUser()==null)
{
startActivity(new Intent(this,Giris.class));
finish();
}
setContentView(R.layout.activity_main);
@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Navigation itemlerinin click olaylarını burada yapıyoruz.
int id = item.getItemId();
if (id == R.id.nav_kullanici)
{
startActivity(new Intent(MainActivity.this,Hesabim.class));
}
else if (id == R.id.nav_hatirlatma)
{
startActivity(new Intent(MainActivity.this,AyarlarActivity.class));
}
else if (id == R.id.nav_ipucu)
{
startActivity(new Intent(MainActivity.this,IpuclariSayfasi.class));
}
else if (id == R.id.nav_oyla)
{
}
else if (id == R.id.nav_cikis)
{
firebaseAuth.signOut();
finish();
startActivity(new Intent(MainActivity.this, Giris.class));
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
您是否嘗試直接發送到FCM令牌？ –
不，我該怎麼做？但我沒有發送消息。我想收到消息。 –
順便說一句，我想在Android模擬器上接收消息。這個可以嗎？ –
