[android-developers] app2sd restrictions - sharing a workaround to allow moving your app to SD card
Android recommends that certain apps should not be moved to SD card, e.g. alarm clocks, etc. See http://developer.android.com/guide/appendix/install-location.html The reason for that is, among other things, that when the sd card is unmounted, registrations with the alarm service are canceled, and the app is no longer accessible. When the SD card is mounted again, there is no way to launch the app to reregister those services. So how do you get such apps to work on SD card anyways? I got my app (Gentle Alarm) to work on SD card with a little trick that I share here. Notice: Of course the app won't work if the SD card is unmounted. So this is NOT a solution for apps that need to remain accessible all the time such as live wallpapers. 1) Create an additional small app that remains in memory. If you have a widget for your app, you can use that as widget must stay in internal memory anyways. I will call this app B. 2) If the SD card is unmounted, your app A is no longer accessible. App B can notify the user accordingly if desired. 3) If the SD card is mounted again, there is no way to start app A directly. But app B can listen to the event that external apps are now available and then send an event to app A which can then reregister anything that got broken by unmounting the sd card (e.g. alarm service). 4) If you need to start your app right after a reboot, app A can no longer be started after a reboot because the SD card is not mounted yet. You can simply get rid of the event receiver because step 3 already accomplishes what you need. After reboot, the sd card eventually is mounted and the external apps will become available. App B will listen to this even and trigger app A. Hope this will help some people to move their apps to the sd card. My app has been used with this feature for 3 months by 40+ users and I had no complaints.

[android-developers] app2sd - not working
I've just updated my app so the user can choose to install it on the sd card or not. But I keep getting some comments that it's not possible for them to install it on the sd card. Can anyone see if I've made anything wrong or if you have any other suggestions?

Re: [android-developers] app2sd - not working
Just a guess: the problem might be here: uses-sdk android:minSdkVersion=4 / you should probably also specify the targetSdkVersion to be = 8. Again, it's just a guess ;) On Wed, Jan 5, 2011 at 11:51 AM, André pha...@hotmail.com wrote: I've just updated my app so the user can choose to install it on the sd card or not.

[android-developers] app2sd backward compatibility
Hello guys, I recently enabled the app2sd functionality in my app. To remain compatible with Android 1.5 i left intentionally the minSdkVersion at 3 and added android:installLocation=preferExternal attribute to my manifest. Basically I followed what is listed in the following article: http://developer.android.com/guide/appendix/install-location.html When i test the apk on my NexusOne (2.2) the app goes to the SD card, perfect! But when i publish the app on the market and install the same apk from the market on the same Nexus, the app2sd function is missing, I can't install it to my SD card. Has anybody had the same problem before? Thanks in advance! Laszlo -- You received this message because you are subscribed to the Google Groups Android Developers group.
