Could not load native library jni_latinime.so Android

Issue

It gives an error and couldn't load .so files. I searched it on the internet and read many things but didn't find an answer. I tried to use System.loadLibrary("jni_latinime") but it failed again. Please give me any advice. Thanks.

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.android.inputmethod.latin-1/base.apk"],nativeLibraryDirectories=[/data/app/com.android.inputmethod.latin-1/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libjni_latinime.so"

Solution

1.Set NDK PATH

2.add this in build.gradle

 sourceSets.main {
         jni.srcDirs = []
          jniLibs.srcDir 'src/main/libs'
     }

3.Create a Jni folder inside SRC direactory

4.Create- Android.mk--inside jni folder-

5.add in Android.mk file

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := "module name"//added inside system.load(); ** i used addjni**

LOCAL_SRC_FILES := Native.c   //create a native.c class
LOCAL_LDLIBS := -llog -ljnigraphics
include $(BUILD_SHARED_LIBRARY)

6.Create a file Application.mk---inside jni folder---------------- and write this

  APP_ABI := all

7.add inside MainActivity

 public class MainActivity extends AppCompatActivity {

 static {
     System.loadLibrary("addjni");
 }
 TextView sum;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
     sum=(TextView)findViewById(R.id.sum);
     int as=Native.sumoftwo(210,15);
     Log.e("sum",as+"");
     sum.setText(as+"");

 }

}

8.create a new NativeNDK.c

//inside jni folder and add this //jave_packageName_Native(Classname)_(methodname) replace(. with -)

 include<string.h>
 include<jni.h>
 jint JNICALL Java_droider_Native_sumoftwo(JNIEnv*  env , jclass obj,jint   a,jint b)   

      {
        jint total=(a+b);
         return total;
       }

9. go to studio terminal and inside type command

cd app\src\main>D:\android-ndk-r10d\android-ndk-r10d\ndk-build APP_PLATFORM=android-8 enter

10. Native.c inside main/src

 public class Native {
       public native static int sumoftwo(int a,int b);
        static {
                System.loadLibrary("addjni");
        } 
    }

11.copy all .so from libs and paste into jinLibs if exist else create and paste
