Android Studio does not recognize 'MediaProjectionManager' class

Question

I am trying to make an app for screenshot. I've found there are several guides for using MediaProjectionManager for that purpose.

This is one of them.

http://www.truiton.com/2015/05/capture-record-android-screen-using-mediaprojection-apis/

I copied the source exactly but the Android studio just can't handle the MediaProjectionManager.

These are the build error messages.

Error:(23, 32) error: package android.media.projection does not exist

Error:(24, 32) error: package android.media.projection does not exist

Error:(32, 13) error: cannot find symbol class MediaProjectionManager

Error:(35, 13) error: cannot find symbol class MediaProjection

Error:(171, 66) error: package MediaProjection does not exist

And these are the lines that are causing the error.

import android.media.projection.MediaProjection;

import android.media.projection.MediaProjectionManager;

I'm sure these class paths for MediaProjection and MediaProjectionManager are correct. A little help please.

Answer 1

MediaProjection is added in API level 21 (Android 5.0). The "compileSdkVersion" of your Module needs to >= 21. e.g

android {
    compileSdkVersion 26
    ...
    defaultConfig {
        minSdkVersion 21
        ...
    }
}
