Android BLE dfu升级

dfu升级适用于nordic  nRF51  nRF52 的系统，github上提供了相关升级的库 https://github.com/NordicSemiconductor/Android-DFU-Library 支持 Android 4.3+

gradle配置如下：

implementation 'no.nordicsemi.android:dfu:1.8.1'

在使用前请先配置好BLE的相关权限以及动态权限 读写权限 定位等可以使用EasyPermission配置

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED" />

第一步 我们创建一个service集成DfuBaseService

public class DfuService extends DfuBaseService {
    public DfuService() {
    }

    @Override
    protected Class<? extends Activity> getNotificationTarget() {
        return NotificationActivity.class;
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        throw new UnsupportedOperationException("Not yet implemented");
    }
}

第二步 创建一个NotificationActivity

public class NotificationActivity extends Activity {
    @Override
    protected void onCreate(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, UpdateZipActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.putExtras(getIntent().getExtras()); // 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();
    }
}

其中UpdateZipActivity即为处理升级业务的界面

在这里要根据你的业务需求来，可以把升级包打包在apk里，也可以做成下载后升级的情况

如果是打包在apk里可以按下面做，如果你是下载的情况只需要改starter.setZip(uri, path); 传入文件uri和路径即可  

private DfuServiceInitiator starter; 


starter = new DfuServiceInitiator(mac).setDeviceName("Smart Lock").setKeepBond(false).setPacketsReceiptNotificationsEnabled(true).setPacketsReceiptNotificationsValue(10);
        // If you want to have experimental buttonless DFU feature supported call additionally:
        starter.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true);
        starter.setZip(R.raw.update24); //setDeviceName为设备过滤条件 setzip传入raw文件的路径即可

@Override
protected void onResume() {

DfuServiceListenerHelper.registerProgressListener(this, mDfuProgressListener); //监听升级进度
starter.start(this, DfuService.class); //启动升级服务

}

/**
 * dfu升级监听
 */
private final DfuProgressListener mDfuProgressListener = new DfuProgressListener() {
    @Override
    public void onDeviceConnecting(String deviceAddress) {
        Log.i("dfu", "onDeviceConnecting");
        proBar.setIndeterminate(true);
        airUpgradeTv.setText(R.string.dfu_status_connecting);
    }

    @Override
    public void onDeviceConnected(String deviceAddress) {

    }


    @Override
    public void onDfuProcessStarting(String deviceAddress) {
        proBar.setIndeterminate(true);
        airUpgradeTv.setText(R.string.dfu_status_starting);
    }

    @Override
    public void onDfuProcessStarted(String deviceAddress) {
        Log.i("dfu", "onDfuProcessStarted");
    }

    @Override
    public void onEnablingDfuMode(String deviceAddress) {
        Log.i("dfu", "onEnablingDfuMode");
        proBar.setIndeterminate(true);
        airUpgradeTv.setText(R.string.dfu_status_switching_to_dfu);
    }

    @Override
    public void onProgressChanged(String deviceAddress, int percent, float speed, float avgSpeed, int currentPart, int partsTotal) {
        Log.i("dfu", "onProgressChanged");
        Log.i("dfu", "onProgressChanged" + percent);
        proBar.setProgress(percent);
        proBar.setIndeterminate(false);
        airUpgradeTv.setText(percent + "%");
    }

    @Override
    public void onFirmwareValidating(String deviceAddress) {
        Log.i("dfu", "onFirmwareValidating");
        proBar.setIndeterminate(true);
        airUpgradeTv.setText(R.string.dfu_status_validating);
    }

    @Override
    public void onDeviceDisconnecting(String deviceAddress) {
        Log.i("dfu", "onDeviceDisconnecting");
    }

    @Override
    public void onDeviceDisconnected(String deviceAddress) {
        Log.i("dfu", "onDeviceDisconnected");
        proBar.setIndeterminate(true);
        airUpgradeTv.setText(R.string.dfu_status_disconnecting);

    }

    @Override
    public void onDfuCompleted(String deviceAddress) {

        airUpgradeTv.setText(R.string.dfu_status_completed);
        proBar.setProgress(100);
        proBar.setIndeterminate(false);
        //升级成功
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                // if this activity is still open and upload process was completed, cancel the notification
                final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                manager.cancel(DfuService.NOTIFICATION_ID);


            }
        },200);


    }

    @Override
    public void onDfuAborted(String deviceAddress) {
        Log.i("dfu", "onDfuAborted");
        //升级流产，失败
        airUpgradeTv.setText(R.string.dfu_status_aborted);
        // let's wait a bit until we cancel the notification. When canceled immediately it will be recreated by service again.
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(UpdateZipActivity.this, "升级出错", Toast.LENGTH_SHORT).show();
                // if this activity is still open and upload process was completed, cancel the notification
                final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                manager.cancel(DfuService.NOTIFICATION_ID);
            }

    }

    @Override
