Google + Anmelden: Aktivität wird nicht gestartet

Question

Ich verwende com.actionbarsherlock.app.SherlockActivity in meinem Projekt. Wenn ich versuche, eine andere Aktivität zu starten, bei der ich ein Google+ anmelden muss, tritt dieser Fehler auf. Ich erhalte diesen Fehler auf einem tatsächlichen Gerät, nicht auf dem Emulator. Was denkst du, was ich falsch mache?

I habe auch versucht "setScopes (Scopes.PLUS_LOGIN)" zu benutzen, bin aber auf dasselbe Problem gestoßen.

import com.google.android.gms.common.Scopes; 
// in onCreate() 
mPlusClient = new PlusClient.Builder(this, this, this).setScopes(Scopes.PLUS_LOGIN).build(); 

Ich habe versucht, keytool auch zu starten .... ist androiddebugkey erforderlich? https://developers.google.com/+/mobile/android/getting-started

C:\repos>c:\java\jdk1.6.0_34\bin\keytool.exe -exportcert -alias androiddebugkey -keystore agoyal-release-key.keystore -list -v 
Enter keystore password: 
keytool error: java.lang.Exception: Alias <androiddebugkey> does not exist 
    java.lang.Exception: Alias <androiddebugkey> does not exist 
    at sun.security.tools.KeyTool.doPrintEntry(KeyTool.java:1339)

Answer 1

für den Befehl keytool, wenn Sie Ihren eigenen Freigabeschlüssel verwenden, sollte der Alias ​​das nicht „androiddebugkey“ verwendet, um einer Ihres Schlüssel sein.

Answer 2

Etwas stimmt nicht, sind Sie sicher, dass die richtige Logcat-Ausgabe war?

Mit Ihrem Code sollten Sie die android.app.SuperNotCalledException: Activity {LandingActivity} did not call through to super.onCreate() Ausnahme anstelle des Fehlers erhalten, die Sie zeigen.

Auch Ihre public onConnected() Methode in der SignInActivity hat eine falsche Signatur. Der richtige sollte public onConnected(Bundle connectionHint) sein. Es ist wahrscheinlich, dass deine App nicht korrekt kompiliert wurde.
