Question

我＆＃39;当我的应用程序打开时出现问题，因为当应用程序打开时，问题是cameraource不是null或类似的东西，并且不能在所有手机上运行。

这些是错误：

这些是崩溃应用程序的功能：

private void startIfReady() throws IOException {
    if (mStartRequested && mSurfaceAvailable) {
        if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        mCameraSource.start(mSurfaceView.getHolder());
        if (mOverlay != null) {
            Size size = mCameraSource.getPreviewSize();
            int min = Math.min(size.getWidth(), size.getHeight());
            int max = Math.max(size.getWidth(), size.getHeight());
            if (isPortraitMode()) {
                // Swap width and height sizes when in portrait, since it will be rotated by
                // 90 degrees
                mOverlay.setCameraInfo(min, max, mCameraSource.getCameraFacing());
            } else {
                mOverlay.setCameraInfo(max, min, mCameraSource.getCameraFacing());
            }
            mOverlay.clear();
        }
        mStartRequested = false;
    }
}

Android相机无法连接到服务
