How to setup an emulator running API 25 using a build matrix on Travis CI? : <p>I am attempting to setup Travis CI so that it runs instrumentation tests on an emulator running API 25. Travis runs the tests to completion on API 4/10/19, but fails to startup the emulator for API 25, with the following message:</p>

<pre><code>$ echo no | android create avd --force -n test -t $ANDROID_TARGET --abi $ANDROID_ABI
Valid ABIs: no ABIs.
Error: Invalid --abi armeabi-v7a for the selected target.
</code></pre>

<p>The output of <code>android list targets</code> shows that the API 19 emulator has a Tag/ABI, whereas the API 25 emulator does not:</p>

<pre><code>id: 7 or "android-19"
     Name: Android 4.4.2
     Type: Platform
     API level: 19
     Revision: 4
     Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, WXGA720, WXGA800, WXGA800-7in
 Tag/ABIs : default/armeabi-v7a

id: 11 or "android-25"
     Name: Android 7.1.1
     Type: Platform
     API level: 25
     Revision: 3
     Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, WXGA720, WXGA800, WXGA800-7in
 Tag/ABIs : no ABIs.
</code></pre>

<p>How can I fix this so that the API 25 emulator launches and runs the tests?</p>
