android studio上的NDK构建错误

Question

我是NDK的新手,所以我在构建项目时遇到错误:

Error:Execution failed for task ':app:transformNativeLibsWithStripDebugSymbolForDebug'.
java.io.IOException: Failed to delete E:\startUpCode\OpenCvDemo\NDKTest\app\build\intermediates\transforms\stripDebugSymbol\debug\folders\2000\1f\main\lib\mips

这是我的cpp代码

#include <com_nickworld_ndktest_NativeClass.h>


JNIEXPORT jstring JNICALL Java_com_nickworld_ndktest_NativeClass_getMessageFromJNI
    (JNIEnv *env, jclass obj){
return env->NewStringUTF("This is the message from JNI");

android.mk文件

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_SRC_FILES := com_nickworld_ndktest_NativeClass.cpp

LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyLib


include $(BUILD_SHARED_LIBRARY)

Application.mk

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-16

MainActivity.java

public class MainActivity extends AppCompatActivity {

static {
    System.loadLibrary("MyLibs");
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

((TextView) findViewById(R.id.txtView)).setText(NativeClass.getMessageFromJNI());
}
}

我需要帮助来解决这个错误,我没有得到我在做错的地方.谢谢

尝试E:\startUpCode\OpenCvDemo\NDKTest\app\build\intermediates手动删除。然后再次尝试构建。
