To allow installation on external storage and remain compatible with versions lower than API Level When your application is installed on a device with an API Level lower than 8, the android:installLocation attribute is ignored and the application is installed on the internal storage. Caution: Although XML markup such as this will be ignored by older platforms, you must be careful not to use programming APIs introduced in API Level 8 while your minSdkVersion is less than "8", unless you perform the work necessary to provide backward compatibility in your code.
When the user enables USB mass storage to share files with their computer or otherwise unmounts or removes the external storage , any application installed on the external storage and currently running is killed. The system effectively becomes unaware of the application until mass storage is disabled and the external storage is remounted on the device. Besides killing the application and making it unavailable to the user, this can break some types of applications in a more serious way.
In order for your application to consistently behave as expected, you should not allow your application to be installed on the external storage if it uses any of the following features, due to the cited consequences when the external storage is unmounted:. If your application uses any of the features listed above, you should not allow your application to install on external storage.
By default, the system will not allow your application to install on the external storage, so you don't need to worry about your existing applications. However, if you're certain that your application should never be installed on the external storage, then you should make this clear by declaring android:installLocation with a value of " internalOnly ". Though this does not change the default behavior, it explicitly states that your application should only be installed on the internal storage and serves as a reminder to you and other developers that this decision has been made.
In simple terms, anything that does not use the features listed in the previous section are safe when installed on external storage. Large games are more commonly the types of applications that should allow installation on external storage, because games don't typically provide additional services when inactive. When external storage becomes unavailable and a game process is killed, there should be no visible effect when the storage becomes available again and the user restarts the game assuming that the game properly saved its state during the normal Activity lifecycle.
If your application requires several megabytes for the APK file, you should carefully consider whether to enable the application to install on the external storage so that users can preserve space on their internal storage.
