Android 使用空表面纹理设置相机时抛出运行时异常
Android runtime exception thrown when setting camera with null surface texture
我开发了一个后台摄像头，但是我有一个奇怪的事情。我的应用程序可以在这些设备上正常运行：三星 Note2 android：4.1.2、4.4.2、LG G3 android 4.4.2、华硕 android 4.4.2。但是，这在这些设备中失败，例如 REDMI android:4.2.2、Samsung S6：5.1、Samsung note3：4.3、Sony Xperia：4.4.4、Sony Z3：4.4.4。想知道原因和解决方法。谢谢大家
我的清单：
使用权限 android:name="android.permission.CAMERA"
使用功能 android:name="android.hardware.camera"
使用功能 android:name="android.hardware.camera.autofocus"

我假设您的清单包含所有必要的权限？当我遇到类似问题时，解决方案是必须异步加载任务。如果是这种情况，您将需要一个 AsyncTask 来打开相机或拍摄照片或两者兼而有之。
