您好，1.在Android6.0设备以上运行需要设置动态权限，请问一下你是否对app开启了动态权限呢？

2.在grandle文件中加上

 sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

Comments

sourceSets {
    main{
        java.srcDirs = ['src/main/java', 'src/main/aidl']
        resources.srcDirs = ['src/main/java', 'src/main/aidl']

        aidl.srcDirs = ['src/main/aidl']
        res.srcDirs = ['src/main/res']
        jniLibs.srcDirs = ['src/main/libs','libs']
    }
}

动态权限也加了，用的hipermission，

    /**
     * 12. 检查APP所需权限
     * 
     */
    public void checkPermissions() {

        if (Build.VERSION.SDK_INT >= 23) {
            List<PermissionItem> permissionItems = new ArrayList<PermissionItem>();

            permissionItems.add(new PermissionItem(Manifest.permission.READ_PHONE_STATE, "设备状态", R.drawable.permission_ic_phone));
            permissionItems.add(new PermissionItem(Manifest.permission.WRITE_EXTERNAL_STORAGE, "SD存储卡", R.drawable.permission_ic_storage));
            permissionItems.add(new PermissionItem(Manifest.permission.ACCESS_FINE_LOCATION, "位置服务", R.drawable.permission_ic_location));

//            permissionItems.add(new PermissionItem(Manifest.permission.MOUNT_UNMOUNT_FILESYSTEMS, "文件管理", R.drawable.permission_ic_location));
            permissionItems.add(new PermissionItem(Manifest.permission.INTERNET, "网络服务", R.drawable.permission_ic_location));
            permissionItems.add(new PermissionItem(Manifest.permission.ACCESS_NETWORK_STATE, "网络状态", R.drawable.permission_ic_location));
            permissionItems.add(new PermissionItem(Manifest.permission.ACCESS_WIFI_STATE, "WIFI状态", R.drawable.permission_ic_location));
//            permissionItems.add(new PermissionItem(Manifest.permission.WRITE_SETTINGS, "创建文件夹", R.drawable.permission_ic_phone));
            permissionItems.add(new PermissionItem(Manifest.permission.CHANGE_WIFI_STATE, "位置服务", R.drawable.permission_ic_phone));

            HiPermission.create(this)
                    .permissions(permissionItems)
                    .checkMutiPermission(new PermissionCallback() {
                        @Override
                        public void onClose() {
                            Log.e(TAG, "用户取消权限申请");

                            finish();
                        }

                        @Override
                        public void onFinish() {

                            Log.e(TAG, "所有权限申请完成");

                            initView();
                        }

                        @Override
                        public void onDeny(String permission, int position) {
                            Log.e(TAG, "用户拒绝权限申请：" + permission);
                        }

                        @Override
                        public void onGuarantee(String permission, int position) {
                            Log.e(TAG, "用户允许权限申请：" + permission);
                        }

                    });
        }
        else{
            initView();
        }
    }

您好，麻烦将报错信息详细地贴出来看一下

---

调试调用在Environment.initialization(this);方法的如下函数中

    checkAndLoadLibrary64(var0);

执行通过trycatch捕获到的错误是

java.lang.NullPointerException: Attempt to get length of null array

---

您好，在app的build.gradle的defaultConfig标签下添加如下标签，armeabi-v7a也可以换成您的工程使用的so文件。

  ndk {
            abiFilters "armeabi-v7a"
        }

---

嗯，好了，这些库文件有64位的吗？我需要在什么地方下载？

---

您好，不好意思，目前我们没有提供64位的库，提供了32位的库。您可以使用armeabi、armeabi-v7a
