title: How to manually built ndk-build (shared library) in existing android studio project
body: <p>I have an existing android studio project. I have made shared library named <em>libtst.so</em> using ndk with proper jni functions. I have put the library in the following directory<br>
  "src/main/jniLibs/armeabi-v7a/libtst.so"</p>
  
  <p>But while running the project <strong>System.loadLibrary("tst");</strong> cannot work showing following message.</p>
