ExoPlayer Creator

An Android app that can create ExoPlayer 2 video players, HTML5 video players, and video players that play back what you recorded (called Camcorder players in-app) instantly, developed in MIT App Inventor.

ExoPlayer Creator primarily uses the ExoPlayer for App Inventor extension to create ExoPlayer initializations, and is a modified version of the 1.0.4 AIA version of the ExoPlayer for App Inventor demo.

Extensions	First Used
ExoPlayer for App Inventor	v1 and beyond
UpdateMyApp	v1.4.1

Compatibility

ExoPlayer Creator has been tested on the following devices with the following results:

Device	Compatible?	Real Device/VM
Android 15	Yes	VM
Android 14	Yes	Real Device
Android 8	Yes	VM
Android 5	No	VM

Compatibility-wise, most versions of Android work just fine with the app, but if you're using Android 7 or below, note that I either haven't tested the app on those devices or the app failed to function as intended.

Make sure you have a WebView installed, or else the HTML5 player won't work because it relies on a WebView to display the player. This is important in VMs since unlike commercial devices they are meant more for developer purposes and thus lack some important tools, like the Play Store (some Android SDKs do not include it), WebViews, etc.

Issues (that can't really be fixed)

On Android 5, a severe codec issue happens when loading any video, in both ExoPlayer and the HTML5 player. This is most likely due to the fact that Android 5 does not support the latest video codecs.

And on any Android version, URLs that are signed using self-signed certificates return a source error in any video player in the app that supports using video URLs, this is normal behavior in Android and it cannot be fixed because Android does not allow bypassing this check.

Fun Facts!

The VMs were actually Android Virtual Devices that were created in Android Studio.

The app's size is about 28 MB once installed, but the APK is a rather small 4.3 MB
