How to change target build on Android project?

Question

I currently have an Android project in Eclipse.

I created it with a target build of 1.5 (sdk 3).

Now I want to change it so that it has a minSdk of 3 and tar

Answer 1

Another way on the command line if you are using ant is to use the android.bat script (Windows) or android script (Mac). It's in $SDK_DIR/tools.

If you say,

android.bat update project --path .  --target "android-8"

it will regenerate your build.xml, AndroidManifest.xml, etc.

Answer 2

Well I agree with Ryan Conrad on how to do it in eclipse, have you ensured you have changed your manifest.xml?

 <uses-sdk android:minSdkVersion="3" />
 <uses-sdk android:targetSdkVersion="8" />

Answer 3

I had this problem too. What worked for me was to first un-check the previously selected SDK version before checking the new desired version. Then click okay.

Answer 4

As Mike way says. Change target BEFORE doing anything in your project that requires a higher target like android:installLocation="auto".

Answer 5

The problem sometimes occurs when there are errors in the project.

For instance, if your project is configured with a target of 3.2 but the 3.2 libraries are not available, you will not be able to change the version to 4.0!

The usual (perhaps brutal) solution I use is to create a new project with the correct target and copy src, res and manifest into the new project.

Update:

This seems to work:

1. Change the selected through the build properties as normal
2. Manually edit project.properties AND default.properties to make sure they both reflect the desired target.
3. Close the project and re-open it

I always run Android Tools | Fix Project Properties after making any changes to the build target.

Answer 6

as per 2018, the targetSdkVersion can be set up in your app/build.gradle the following way:

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
       ...
       targetSdkVersion 26
    }
    ...
}

if you choose 26 as SDK target, be sure to follow https://developer.android.com/about/versions/oreo/android-8.0-migration
