Create plugins

See Support Thread

Implementing plugins is as easy as copying one file to your source, and implementing a BroadcastReceiver that listens for the search queries (sent as text). All this is demonstrated in the support thread.

AndroidManifest.xml

<uses-permission android:name="com.mohammadag.googlesearchapi.permission.ACCESS_GGOGLE_SEARCH_API" />
...
<receiver android:name=".now.GoogleSearchReceiver" >
    <intent-filter>
        <action android:name="com.mohammadag.googlesearchapi.NEW_SEARCH" />
    </intent-filter>
</receiver>

GoogleSearchReceiver.java

public class GoogleSearchReceiver extends BroadcastReceiver {
    @Override
	public void onReceive(Context context, Intent intent) {
		String queryText = intent.getStringExtra(GoogleSearchApi.KEY_QUERY_TEXT);
		Toast.makeText(context, "Test de API GOOGLE: " + queryText, Toast.LENGTH_SHORT).show();
	}
}

How to Hack Google API

XPosed tutorial: https://github.com/rovo89/XposedBridge/wiki/Development-tutorial

Please add new hooks in file and make a PR
Key is Google search version, and value is the className
File: hooksversion.properties

Find apk on device and copy to PC

adb pull /data/app/com.google.android.googlequicksearchbox-1/base.apk
OR adb pull /data/app/com.google.android.googlequicksearchbox-2/base.apk

Unpack and decompile (use: Apktool

java -jar apktool_2.2.2.jar d base.apk

We need to find out which method is called after the text is recognized

grep -Ril --include *.smali "setFinalRecognizedText"

Open textin file editor (Will need a basic knowledge of smali / bytecode) I found two promising methods in the files below:

smali_classes2/com/google/android/apps/gsa/search/core/service/m.smali smali/com/google/android/apps/gsa/search/shared/overlay/a/v.smali

The name in the hook must be the name of the class. On app, click in settings > Change Hooks

com.google.android.apps.gsa.search.core.service.m
