Hello,
I'm trying to use the plugin on an Android (6.0.1) but when I call the recognizeText method I got this error :

Hey! Recently I had the same problem and managed to resolve it by changing dependency name in platforms/android/build.gradle from compile project(':tess-two') to compile 'com.rmtheis:tess-two:7.0.0' (right after // SUB-PROJECT DEPENDENCIES END comment). If in any case you dont want to change dependency, there is another fix: adding

static{
    System.loadLibrary("jpgt");
    System.loadLibrary("pngt");
    System.loadLibrary("lept");
    System.loadLibrary("tess");
  }

to TesseractPlugin.java file.
