Crash with Api 23 on Galaxy Nexus Emulator

When I try to run the demo application on a emulator which uses the API 23 I get the following exception and the app crashes:
D/SDKRelativeJNI: Couldn't load lib E/art: No implementation found for java.lang.String dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString() (tried Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString and Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString__) E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #1 Process: com.dji.importSDKDemo, PID: 5379 java.lang.UnsatisfiedLinkError: No implementation found for java.lang.String dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString() (tried Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString and Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString__) at dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString(Native Method) at dji.sdk.sdkmanager.DJISDKManager.<clinit>() at com.dji.importSDKDemo.MainActivity$1.run(Unknown Source)

class DJIError and DJISDKError not available

There is a typo in the tutorial as well as the code in MainActivity.java

The two import modules should be:

import dji.common.error.DJIError;
import dji.common.error.DJISDKError;

instead of:

import dji.sdk.base.DJIError;
import dji.sdk.base.DJISDKError;

android API 22 and below not supported

Don't work for Android API 22,21,20,19. private void startSDKRegistration() { never get called.

// When the compile and target version is higher than 22, please request the following permission at runtime to ensure the SDK works well.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkAndRequestPermissions();
}

Does the app really need so many permissions?

The list of permissions is quite large - see below

private static final String[] REQUIRED_PERMISSION_LIST = new String[]{
            Manifest.permission.VIBRATE,
            Manifest.permission.INTERNET,
            Manifest.permission.ACCESS_WIFI_STATE,
            Manifest.permission.WAKE_LOCK,
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.ACCESS_NETWORK_STATE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.CHANGE_WIFI_STATE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.BLUETOOTH,
            Manifest.permission.BLUETOOTH_ADMIN,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.READ_PHONE_STATE,
    };

Please also see here https://github.com/DJI-Mobile-SDK-Tutorials/Android-ImportAndActivateSDKInAndroidStudio/blob/master/ImportSDKDemo/app/src/main/java/com/dji/importSDKDemo/MainActivity.java#L37 and here https://github.com/DJI-Mobile-SDK-Tutorials/Android-ImportAndActivateSDKInAndroidStudio/blob/master/ImportSDKDemo/app/src/main/AndroidManifest.xml#L5

Why does the app need Manifest.permission.READ_PHONE_STATE? android.permission.MOUNT_UNMOUNT_FILESYSTEMS? (the latter is even shown as not allowed for the 3rd party apps on Android)

注册失败，Register sdk fails,please check the bundle id and network connection!

把这个demo编译通过，并在实体机上打开，却显示注册失败，密钥我已经填充，网络也已连接成功。

Build gradle failed after adding DJI module dependencies

Hello,
I am just followed all the step in this tutorial https://developer.dji.com/mobile-sdk/documentation/application-development-workflow/workflow-integrate.html but I stuck at the part to build gradle after adding DJI module dependencies. This is my error, please help me !

MOUNT_UNMOUNT_FILESYSTEMS is only granted to system apps

Following the official documentation https://developer.dji.com/mobile-sdk/documentation/android-tutorials/ImportAndActivateSDKInAndroidStudio.html developers should add a lot of permissions:

    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />

Some of them android.permission.MOUNT_UNMOUNT_FILESYSTEMS has errors/security issue (from play market):

This is maybe this is not issue, but question: Is dji sdk will be workable (or partically workable) if I remove the android.permission.MOUNT_UNMOUNT_FILESYSTEMS permission?

Maybe missing steps to add layouts

In the readme.md there is no mention about editing layout files, that may be confusing.

Manifest deprecated for android 12

Build gives the error:
Manifest merger failed : android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

Import SDK Demo app is not working

This demo app not is working on my Samsung Galaxy S7 Edge device with Android 6.0.1 OS.
Internet connectivity to the device is fine, I imported the project to Android Studio, install and run.
Android Studio Version : 2.3.1
Gradle Version set as : 2.10
App Key is also generated and inserted in the Manifest file.

Below is the app screen shot with error message.

Help me on the DJI_Mapkit-Mapbox has stopped

I am now trying to connect to my Mavic 2 pro. However, I am still outside the door. Please help me with it.
First of all, when I download the code, it cannot run and lots of errors occured.
Secondly, when I come accross the DJISDKManager.getInstance().registerApp() with debug mode, everytime it failed here. This time I delete the assync and run it direct.
Thirdly, I have tried to remove MainActivity.this.getApplicationContext() with MainActivity.this, it still filled. Why?

ImportSDKDemo does not work

I state that I am still trying to test it in the Android Studio emulator.
I load the code into the emulator, give all permissions and then the page closes with the message "registering, pls wait" and never gives the success message. (I have already entered the app key in the manifest)
Thanks in advance for any help.

• DJI Android SDK version : DJI Mobile SDK 4.2.1
• Android system version : Android 7.1
• Android device : OnePlus One
• Android Studio version : 2.3.2
  I've inserted the API key in it. I guess the reason is that Chinese firewall, but I've tried VPN and Shadowsocks. It didn't work, too.

Issues with ImportSDKDemo

1. It cannot resolve the BaseProductListener
   

2. It cannot resolve the method mProduct.setBaseProductListener(...)
   

How to solve those 2 problems?
