App stürzt beim Neustart ab

Question

Ich habe ein paar Posts mit dem gleichen Fehler gesehen. Keiner von ihnen hat jedoch bisher eine funktionierende Lösung für mein Problem angeboten.

Ich habe zwei Aktivitätsklassen, MainActivity und GameActivity. MainActivity startet GameActivity bei einem Tastendruck. Wenn ich die Zurück-Taste an meinem Telefon drücke, geht es zurück zur Hauptaktivität. Allerdings, wenn ich die Taste erneut drücken, um eine neue GameActivity zu starten, bin ich aufgefordert, mit einem Fehler auf der Codezeile zeigt

setContentView(R.layout.activity_game); 

Fehler:

Irgendwelche Eingaben zu diesem Problem?

Answer 1

Unter der Annahme, dass Ihre GameActivity beginnt richtig das erste Mal, aber nach BACK drücken (zu MainActivity zurückzukehren) und dann beginnen, die GameActivity Abstürzen (wegen OutOfMemory), wahrscheinlich bedeutet, dass Sie nicht richtig und vollständig reinigen, wenn das Original Instanz von GameActivity endet.

Von dem Code, den Sie gepostet haben, haben Sie wahrscheinlich ein Speicherleck. Dieser Code:

gameView = (GameView)findViewById(R.id.gameView); 
gameView.setGameActivity(this); 
gameThread = new Thread(gameView); 
gameThread.start(); 

gibt einen Verweis auf gameView-gameThread. gameView hat einen Verweis auf die Instanz GameActivity. Wenn Sie diese Thread nicht ordnungsgemäß bereinigen, wenn die Instanz GameActivity beendet wird, kann der Garbage Collector die alte GameActivity und alle Ressourcen (einschließlich Ihrer Bilder) nicht wiederherstellen, bevor Sie versuchen, die zweite Instanz zu starten. Sie können Heap-Analyse- und Heap-Debugging-Tools verwenden, um Speicherlecks wie diese zu finden.

Answer 2

Ich denke, dass die Bildgröße, die Sie für die App verwendet haben, Ihre Zelle möglicherweise nicht unterstützt. Versuchen Sie, die Größe der Bilder zu minimieren.
