You need to add
<meta-data android:name="net.zhuoweizhang.mcpelauncher.api.targetmcpeversion" android:value="(the MCPE version you tested this addon with)"/>
to your addon's AndroidManifest.xml: for example,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.zhuoweizhang.mcpelauncher.addon.bow"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="17"/>
<application android:label="@string/app_name" android:hasCode="false">
<meta-data android:name="net.zhuoweizhang.mcpelauncher.api.nativelibname" android:value="zhuoweibow"/>
<meta-data android:name="net.zhuoweizhang.mcpelauncher.api.targetmcpeversion" android:value="0.11.0"/>
</application>
</manifest>
