　　　　How to get the log from device ?

　　　  Detail:  Get the log from device, and write to the local file .

Google Source jar:

　      Use the methods in ddmlib.jar mostly:　　

　　　　　　 import com.android.ddmlib.AndroidDebugBridge;
　　　　　　import com.android.ddmlib.AndroidDebugBridge.IDeviceChangeListener;
　　　　　　import com.android.ddmlib.IDevice;

　

The concrete process:　　   

　　　 First step :   connect the devices through ADB                            

    //import package

    import com.android.ddmlib.AndroidDebugBridge;

    import com.android.ddmlib.IDevice;

    //Creat  AndroidDebugBridge 和 device class object

    private AndroidDebugBridge mBridge;

    private IDevice mDevice;

    //Get the device object you want connect

    String serial_number = "INV121501088";

    mBridge = AndroidDebugBridge.createBridge(location, true );

    mdevice = findAttachedDevice(deviceIdRegex);

    //Find the device from the devices through AndroidDebugBridge

    private IDevice findAttachedDevice(String deviceIdRegex) {

        Pattern pattern = Pattern.compile(deviceIdRegex);

        for (IDevice device : mBridge.getDevices()) {

            String serialNumber = device.getSerialNumber();

            if (pattern.matcher(serialNumber).matches()) {

                return device;

            }

        }

        return null;

    }

              Second step :   Get the Log to buffer    

  mPrefStore = new PreferenceStore();

  mPrefStore.setDefault(LogCatMessageList.MAX_MESSAGES_PREFKEY,

                 LogCatMessageList.MAX_MESSAGES_DEFAULT);

  mLogcatReceiver= new LogCatReceiver(mdevice, mprefStore);
