Google + Accedi: l'attività non verrà avviata

Question

Sto utilizzando com.actionbarsherlock.app.SherlockActivity nel mio progetto. Quando provo ad avviare un'altra attività in cui dovrò eseguire un accesso Google+, si verifica questo errore. Sto ottenendo questo errore su un dispositivo reale, non sull'emulatore. Cosa pensi che stia sbagliando?

errore

I ho anche provato a utilizzare "setScopes (Scopes.PLUS_LOGIN)" ma ho riscontrato lo stesso problema.

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

ho cercato di iniziare keytool così .... è necessario androiddebugkey? 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) 
    at sun.security.tools.KeyTool.doCommands(KeyTool.java:869) 
    at sun.security.tools.KeyTool.run(KeyTool.java:172) 
    at sun.security.tools.KeyTool.main(KeyTool.java:166) 

Answer 1

per il comando keytool, se si utilizza la chiave di sblocco propria, l'alias dovrebbe essere quella la chiave utilizzata, non "androiddebugkey".

Answer 2

Qualcosa non è giusto, sei sicuro che era l'output logcat corretto?

Con il tuo codice, dovresti ottenere l'eccezione android.app.SuperNotCalledException: Activity {LandingActivity} did not call through to super.onCreate() invece dell'errore che stai visualizzando.

Inoltre, il metodo public onConnected() nello SignInActivity ha una firma non corretta. Quello corretto dovrebbe essere public onConnected(Bundle connectionHint). È probabile che la tua app non sia compilata correttamente.
