I want to update my application. I changed the version code but when I try to install that application it won't succeed.
This error message is shown:
An existing package by the same name with a conflicting signature is
already installed
How to get previous version debug signature and set it in Android studio? Thanks
There are two parameters that remain in your build.gradle file of your app.
versionCode 1
versionName "1.0"
android:versionCode — An integer value that represents the version of the application code, relative to other versions.
android:versionName — A string value that represents the release version of the application code, as it should be shown to users.
Please refer this documentation to know more about this.
Also you can get the VersionName and VersionCode programatically, in this way --
PackageInfo pInfo = getPackageManager().getPackageInfo(this.getPackageName(), 0);
String versionName = pInfo.versionName;
int versionCode = pInfo.versionCode;
EDITED:
Please refer this documentation to create a debug.keystore file.
Hope this helps!
You just need to ensure that your phone doesn't have the same application already installed whilst you are trying to install the same application's new APK.
So before installing the application, follow the following steps: 1. Go to Settings of your phone and look for an option that lists all applications in your phone and try to find whether the application that you are trying to install is already listed. If it is, then uninstall it from there. 2. Usually uninstalling by following step 1 removes the application from your phone however, if you are using a tablet, sometimes Android still keeps the APK file in the downloaded directory. So come out of settings and find out "All files" folder. Look for your app's APK in "downloaded" folder inside "All files" folder and remove it from there too.
Once you have deleted your app by following the above steps then you can go ahead and install your app. Hopefully you won't see "an existing package by the same name with a conflicting signature is already installed" error message.

How much do I have to change in an android project for it to be installed as a new app?
I thought that it would be enough to change the applicationId in the build.gradle file, but I am not able to install the second version of the app without uninstalling the first version. In the play store I get error 910 or error -505 and when installing it manually I get:
Installation failed with message Failed to finalize session : INSTALL_FAILED_CONFLICTING_PROVIDER: Package couldn't be installed in /data/app/net.mindlevel-1: Can't install because provider name net.mindlevel (in package net.mindlevel) is already used by net.veglevel.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
Do I have to change the package name in AndroidManifest.xml too?
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.mindlevel">
And if I have change that, I have to change every single source file to use that package right?
In your manifest, there is a <provider> element with a hardcoded android:authorities attribute. That needs to be changed as well as your applicationId, as there can only be one provider installed for each unique authority.
Okay so i have an application, put up on the playstore.
What i want now, it to create the same application but with debug postfix in the name and it must have everything same.
I want to do this, because i do not want to disturb my original project when i am experimenting stuff,
So what i did was, i copied the project folder from wherever it was to the desktop, original one had the package name com.femindharamshi.spa so i refactored the whole thing to com.femindharamshidebug.spadebug and all changed the app_name in string
but when i try to open this app in the emulator, Android Studio Gives me the following error :
Installation failed with message Failed to finalize session :
INSTALL_FAILED_INVALID_APK: Split_lib_slice_4_apk was defined multiple
times. It is possible that this issue is resolved by uninstalling an
existing version of the apk, if it is present, and then re-installing
Also i do not want to uninstall the original app from the emulator/physical device, i just want to add this app for testing purposes. What should i do ?
Try closing the Android Studio and giving clean and build to the project.
change you application ID in app level build.gradle file and sync the project
applicationId "//pkg id here"
I used to work with Android studio 1.4. yesterday I downloaded the newest version of android Studio 2.1.2 and it did not work well for me, so i reverted to Android studio 1.4.
the problem is, when i tried to run my App, I received a message telling me, "that the apk is already installed on the phone and to reinstall it i have to uninstall the version that is already on the phone".
Actually, I can not uninstall the apk version that is currently on the phone because it contains a huge database, and if i uninstalled it, then the databse content will be lost and i have to do it from the beginning
is there any other solution to run the App "apk" without uninstalling it
i am getting this message:
The easiest and the fastest way is to change application package name.
An appropriate way to do what you want would be to use ProductFlavours.
You start by adding the following to your app's build.gradle:
android {
productFlavors {
dev {
applicationId "com.yourapp.dev" //one in development mode
}
prod {
applicationId "com.yourapp" //the package name for your released app
}
}
}
You can add parameters different for the dev and production apk(s) as BuildConfig fields.
Do study more about it, will be able to implement it in the way you want. You can start with

Just change the applicaitonId property in the app module's build.gradle.

Hope this will help you.

I have already uploaded the beta version, with version code 1,
Now I m trying to upload the new version in Production mode. I am changing the versionCode from 1 to 2 and versionName from 1.0.0 to 1.0.1
Then I am genereating the signed APK.
But when I m trying to upload the apk, its showing "You need to use a different version code for your APK because you already have one with version code 1."
Please help me to get rid of the prob.
(Do it need to delete the previous signed apk file which i have created at the time of generating signed apk and create again)
You most likely changed your versionCode directly in your Manifest file. But if you use Android Studio, final Manifest file is generated and some parts may be overwritten during manifest merging phase (see blog post on what it is). So highlight your app module, press F4 and bump version code on Flavours tab.
I've an android app on the market, which I've built through the online PhoneGap Build service. Now I want to upgrade it to next version, so I create a new app via PhoneGap Build.
Unfortunately, when i try to put them in the market as the app upgrade, it returns me an error, saying that there is a problem in the versionCode. I know that the versionCode in the AndroidManifest must be higher than the previous one, in order to upgrade the app successfully, so I set the version to 1.2.
Which could be the error? Is it possible that the market returns me a false error? I mean, that the error is another one?
Anyone experienced anything like this?Any advice?Thanks to all!
Check that you're updating both the android:versionCode and android:versionName attributes in the manifest.
Also, make sure that the value in versionCode is just an integer (which you increase with each new release). The symbolic version, "1.2", should go in the versionName field.
There are a couple of things that you need to check.
The package name has to be the same and signed with the same key.
Version code problems are usually due to one of two things:
a. android:versionCode is not an integer. This has to be a whole number incremented for each new version. An app can have the same versionName as long as the version Code is higher for the update. First version android:versionCode="1", upgrade versionCode="2"
b. android:versionName has been updated but the versionCode is the same. i.e android:versionName was changed from "1.5" to "1.6" but the versionCode is still set to "1".
