NRF52832空中升级安卓源码

话不多说，上源码

导入官方包

//NRF52*** DFU空中升级SDK
implementation 'no.nordicsemi.android:dfu:1.9.0'

//在AndroidMainfest.xml添加   **是你当前DfuService的路径
<!-- 使用DFU时必须添加否则无法进行 -->
<service android:name="com.**.**.DFU.DfuService"/>

添加DFU文件：

public class DfuService extends DfuBaseService {
    /*
    创建DfuService，实现 getNotificationTarget() 方法，
    在进行DFU时，该方法会返回一个活动类 ，
    该活动通过Intent ,FLAG_ACTIVITY_NEW_TASK标志开启
     */
    @Override
    protected Class<? extends Activity> getNotificationTarget() {
        return NotificationActivity.class;
    }

    @Override
    protected boolean isDebug() {
        return BuildConfig.DEBUG;
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        return null;
    }
}

//用于组织APP的其他实例启动
public class NotificationActivity extends Activity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // If this activity is the root activity of the task, the app is not running
        if (isTaskRoot()) {
            // Start the app before finishing
            final Intent intent = new Intent(this, UpdateActivity.class);//UpdateActivity更新页面
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            Bundle bundle = getIntent().getExtras();
            if(bundle != null) {
                intent.putExtras(bundle); // copy all extras
                startActivity(intent);
            }
        }

        // Now finish, which will drop you to the activity at which you were at the top of the task stack
        finish();
    }
}
