[android-developers] Is there any permission control on the sender of INSTALL_REFERRER?
Hello,
My APP will use action com.android.vending.INSTALL_REFERRER for install
referrer tracking, but seems that I can easily write an small APP to
broadcast intent with this action.
Intent testIntent = new
Intent(com.android.vending.INSTALL_REFERRER);
testIntent.putExtra(referrer,
utm_content={\TEST_BOOLEAN\:true});
sendBroadcast(testIntent);
My question is that whether Android has any permission control on
the sender of com.android.vending.INSTALL_REFERRER?
Thanks.
Br,
posaidong

[android-developers] How will Android uninstall updates for a system app?
Hello Android, We have developed an APP and will be pre-installed as a system APP in some devices. So I have done a lot of tests about upgrade and downgrade, about how they load libraries and how they save data. Now I have a question about uninstall updates. My test is based on Android 4.0 emulator and steps are: 1, Put MyApp_v1.0.apk in /system/app, put necessary libraries in /system/lib. Then MyApp is installed as a system APP. 2, Use command: adb install -r MyApp_v2.0.apk, to upgrade the APP. It's successful, and all the data in /data/data/MyApp are kept unchanged, further more, the new libraries in MyApp_v2.0.apk are installed in /data/data/MyApp/lib. 3, Go to System Setting - App - Manage Application, select MyApp, Tap Uninstall Updates, to downgrade it to the system APP MyApp_v1.0. It's suecessful. But I find in Step 3, when I uninstall updates, the data in /data/data/MyApp are still there, only change is that, the /data/data/MyApp/lib fold gets emptied. That's a little bit of strange to me. My questions are: 1, I have checked different versions(2.1, 2.3.3, 4.0.1) of Android source code, in PackageManagerServce.java, follow the call flow of deleteSystemPackageLI(), the package data folder should be deleted in function removePackageDataLI(), mInstaller.remove(packageName, 0); Why the test result is different as expected? 2, If the behavior - keeping the data unchanged when uninstalling updates, is as designed, that maybe cause some problems. Imaging I add some new configuration item, or change the configuration structure in the new version, after downgrade to old version, this new configuration will not be recognized by the pre-installed system APP. The result is unknown. So can you take a look and explain? Please correct me if my understanding is wrong. Thank you.

Re: [android-developers] Uninstall Updates functionality
Hi Dianne, I have a question about that. When uninstall updates for a pre-installed APP, will system remove the /data/data/package-name/ folder? I have read a little code about the install, seems system will remove it and re-install the APK in /system/app. Just want to confirm. Thanks.

I haven't seen this for any other app (but I haven't looked that hard either). If I had to guess, this is because Maps comes on the firmware and can be updated via the Market. They label it Uninstall Updates because removing the Market package would result in you still having the Maps app, just back to the firmware edition. Is this functionality available to the rest of us devs? If you ship as part of phone firmware, presumably yes. For example, the device manufacturer might ship 1.0 of your app but tell you to push updates via the Market for 1.1, 1.1b, System 3000, Mark V, and 1.1c of your app. Note, though, that this is an educated guess, based on a few conversations, with only a passing resemblance to absolute assurance. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 2.8 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.
