Android insufficient permissions for device

Hi Friends,

I was having an issue when connected my friend's Micromax Doodle to my Ubuntu with the following error
"insufficient permissions for device"

Resolution

  1. Open Terminal
  2. Kill the server by typing the following command
    • $ adb kill-server
  3. Now, start the server
    • $ adb start-server
  4. On your device, a pop-up might come asking for granting the permission
  5. Click on "Yes" for approving the access
  6. Now, check your device status with the following command
    • adb devices
  7. With the above command, you should be able to see devive IMEI and device name
Enjoy the Ubuntu and Android combination :)

Android Virtual Device (AVD) Emulator Creation and Installing APK on Emulator Using Command Line

Dear friends,

Every time whenever we are using most of the Android developers are using Eclipse or some other IDE to create and start the AVD.

I was just thought of using it via command line in my Ubuntu because I was very lazy to start and wait for Eclipse to get ready. I just want to try some apk on Emulator.

Ubuntu Procedure


Open terminal
I was hoping that you had already included the Android tools, platform-tools in PATH. If not just do that else navigate to Android SDK directory

Create AVD:

Syntax: 
$ android create avd -n -t --abi

target-ids are based on the installed Android platforms. Its not the Android API Level.

abi(Application Binary Interface): The ABI is used to control which machine code will run on a given hardware device. For example, for an Android application to run on an x86 device, it is necessary to include x86 ABI support when compiling the application.

Example:
$ android avd -n MyJB -t 12 --abi armeabi-v7a

To view the target-ids list and supported ABI for target-id, execute the following command

$ android list targets

You might be getting some output similar to this

Apple device Untethering Vs Tethering

 Hi friends,

After a successful jailbreak on the iPhone 4, I was confused between Untethered jailbreak and Tethered jailbreak.

Tethered Jailbreak:

Tethered jailbreak on a device requires, the device to be connected to PC/Mac for every reboot.
Advantage:
Less time in the process for jailbreaking.
Disadvantages:
Warranty will be void.
Reboot of the jailbroken device need to be connected to PC/Mac :(

Untethered Jailbreak:
When the device has undergone untethered jailbreaking, it can rebooted like normal device, unlike tethered one.
Advantage: No need of PC/Mac to restart the device
Disadvantage: Warranty will be void

References:

Apple’s Official Response To DMCA Jailbreak Exemption: It Voids Your Warranty

From Apple Support, jailbreaking the device causes issues listed in the below site:

Unauthorized modification of iOS has been a major source of instability, disruption of services, and other issues
