无法在Android模拟器上安装ApiDemos示例项目

Question

I created ApiDemos project using Eclipse - New Project - Sample command. Trying to execute it on Android emulation, I got installation error. Then I opened data/app directory in the File Explorer, DDMS, and removed two files with name starting from ApiDemos (possibly this was incorrect, but this is done already). Now, trying to execute my ApiDemos project, I have:

[2011-11-15 16:23:19 - ApiDemos] Installation error: INSTALL_FAILED_UPDATE_INCOMPATIBLE
[2011-11-15 16:23:19 - ApiDemos] Please check logcat output for more details.
[2011-11-15 16:23:19 - ApiDemos] Launch canceled!

LogCat:

package com.example.android.apis signatures do not match the previously installed version, ignoring!

Is it possible to correct this now? I know that I can re-create emulator, but I would like to solve this problem with existing emulator, just to know how it should be done.

Answer 1

uninstall the previous api demos by your adb command

adb -e uninstall com.example.android.apis

which installed in your emulator.

or try wipe user data while launching the emulator.

Answer 2

First uninstall your application from the emulator:

adb -e uninstall your.application.package.name

Then try to install the application again.

Answer 3

For me, with nexus 5 phone, the following command worked:

adb uninstall <Your_App_Package_Name>

so for your case, where package name is 'com.example.android.apis'

adb uninstall com.example.android.apis

Answer 4

Other option is to go to the application manager. Navigate to the "All" tabs and scroll down to the bottom. Select the application and then from the menu select - uninstall for all users.

Answer 5

您也可以尝试使用“ uninstallAll” gradle任务来完全卸载应用程序
