我在项目中使用Firebase Auth。今天我决定将FCM整合到我的项目中。但我无法通过Firebase控制台发送任何通知。我也尝试重新下载.json文件，但它没有成功。你们对我的问题有什么看法吗？

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/.

我认为问题不在于我的MainActiviy.java，但为了以防万一，我会告诉你。
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;
}
}
答案 0 :(得分：0)
您可能需要检查是否已正确配置应用程序以使用Firebase。在项目的app目录中的beforeConnect: function(handshake, cb) {
// `true` allows the connection
// (`false` would reject the connection)
var token = handshake._query ? handshake._query.token : null;
CipherService.verifyToken(token, function verifyTokenResults(err, decoded, info) {
if (err || !decoded) {
if (err.name === "TokenExpiredError") {
// token expired - user can't connect...
return cb(null, false);
} else {
// some other error...
return cb(err, false);
}
}
// here you may want to do other verification, e.g. the user is active
return cb(null, true);
});
},
文件中添加google-services插件。
build.gradle有关详细信息，请参阅此tutorial。
除此之外，add FCM dependency。确认您的apply plugin: 'com.google.gms.google-services'
文件中是否存在此依赖关系。
app/build.gradle此SO post中的建议解决方案也可能会有所帮助。
