This is what I’m using import android.content.pm.PackageManager; PackageManager pm = context.getPackageManager(); if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) { } All sorts of other fun things to test for are available too – the compass, is location available, is there a front facing camera: http://developer.android.com/reference/android/content/pm/PackageManager.html

Just found out the bug, in this line: mediaRecorder.setVideoSize(sView.getWidth(), sView.getHeight()); after commenting out this line, the code runs perfectly!
Firstly, catch your exceptions in onPictureTaken, leaving empty catch sections is not a good practice. Then, I would add a flag that would prevent from calling takePicture() while previous picture is being saved. Later in your button onClick you would check if it’s ok to call takePicture(). Declare a flag as a member of your … Read more
How to fix this issue for KITKAT? That code has never been appropriate. Fortunately, Android is (finally) taking steps to prevent apps from spoofing more system broadcasts like this.

if (this.getResources().getConfiguration().orientation != Configuration.ORIENTATION_LANDSCAPE) { camera.setDisplayOrientation(90); lp.height = previewSurfaceHeight; lp.width = (int) (previewSurfaceHeight / aspect); } else { camera.setDisplayOrientation(0); lp.width = previewSurfaceWidth; lp.height = (int) (previewSurfaceWidth / aspect); }
