@RequiresPermission(Manifest.permission.CAMERA)
private void startIfReady() throws IOException, SecurityException {
    if (mStartRequested && mSurfaceAvailable) {
        mCameraSource.start(mSurfaceView.getHolder());

            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());

Example 7 with RequiresPermission

use of android.support.annotation.RequiresPermission in project LshUtils by SenhLinsh.

the class LshAppUtils method isAppOnForeground.

/**
     * 判断App是否在前台运行
     * 注意: 该方法是判断APP是否处于栈顶, 处于栈顶但是是关闭屏幕的情况下依然返回true
     */
@RequiresPermission(Manifest.permission.GET_TASKS)
public boolean isAppOnForeground() {
    ActivityManager activityManager = (ActivityManager) LshApplicationUtils.getContext().getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningTaskInfo> tasksInfo = activityManager.getRunningTasks(1);
    if (tasksInfo.size() > 0) {
        // 应用程序位于堆栈的顶层
        if (getPackageName().equals(tasksInfo.get(0).topActivity.getPackageName())) {
            return true;
        }
    }
