How could one change package name of a android app lazarus / 43-Android ---------------------------------------------------------------------- stab · 2012-11-21 21:54 Hi, Tried to change package name from lcltest to testproject2 like this: In batch-file build_debug_apk.bat I changed %APK_PROJECT_PATH%\src\com\pascal\lcltest\LCLActivity.java to %APK_PROJECT_PATH%\src\com\pascal\testproject2\LCLActivity.java in file LCLActivity.java package com.pascal.lcltest; to package com.pascal.testproject2; and in AndroidManifest package="com.pascal.lcltest" to package="com.pascal.testproject2" An apk is created but when I try to run it it fails so something has to be wrong with it, as it works if I don't make these changes. The reason why I want to change package name is that otherwise I get a remark that I'm trying to install same app again even if it is a new one. What should one do to be able to install more than one app? Are the problems due to same package name or something else?
