Use Download Manager for Stuck Google Play Store App Download
For most Android phones, apps are downloaded from the Google Play Store. To clear caches and get the download unstuck, force the Play Store to close.
Use Download Manager to Fix Stuck Android Market App Download
For older phones using, for example, Android 2.1 with Android Market, the process is slightly different.
Private Stores and Sideloading
Some organizations, including large employers, offer custom Android apps outside the Google Play Store. In general, the same process for fixing frozen downloads follows, except instead of performing a force close on the Google Play Store app, force close the proprietary market app. Advanced Android users sometimes sideload (load an app that’s not from the Google Play Market) through various tools. Performing a force close on the sideloading app sometimes works. A broken sideloaded app represents a security and stability risk to the device. It’s best to uninstall the app and try again. If you use the Android Debug Bridge (ADB) to sideload, manage things from the computer you use to access your Android device. ADB was designed for developers and has tools that deal with bugs and breakage. Reconnect your device or restart the ADB service to set things straight first.
