Ich habe versucht, eine Kamera-App für Android zu machen, aber wenn ich versuche, das Bild zu machen, Bugs und ich muss zwingen, nahe. Die LogCat ist:

ich beide camera.takePicture(null, null, photoCallback);
und camera.takePicture(ShutterCallback, rawCallback, photoCallback);
versucht haben, wie Sie sehen können, und ich auch irgendwo gelesen, dass System.gc();
funktionieren könnte, aber es tat es nicht. Außerdem habe ich gelesen, dass ein häufiges Problem war, die Vorschau nach der Aufnahme zu vergessen, aber ich rufe camera.startPreview();
danach an, also weiß ich wirklich nicht, was vor sich geht!
Ich benutze Android 2.3.3 (Motorola Razr). (Es sieht so aus, als hätten viele Leute Probleme mit der Kamera auf Android 2.3.3 ...).
Ich wäre wirklich dankbar, wenn jemand helfen könnte!

Zu welchem Zeitpunkt tritt die Ausnahme genau auf? Können Sie die Kamera starten? – Taha
Ich kann die Kamera starten und sehen die Vorschau, aber es Fehler, wenn ich auf die Schaltfläche klicken, um das Bild zu machen ... – mvitsor
