Some versions of the Samsung Galaxy Tab don’t have the Android Market included with it. You can always visit other Android app web sites to pick up apps, but the Android Market makes it so much easier. Trying to live without it is just annoying. You’ll have to download and install it separately. Here is a way to do it using a Windows PC and the Android SDK.
Note: You have to have root access to perform these steps.
1. Open Settings and select Applications.
2. Check Unknown sources.
3. Download and install the Android SDK. For purposes of this tutorial, we installed the SDK to C:\Android.
5. Download and install Root Explorer. (Since you don’t have Android Market, you’ll have to search for a Root Explorer APK file you can install on your device. Google it, and be sure to buy the app to support the developers. It’s totally worth $4.)
6. From your computer, download Android apps and extract the com.amarket.apk and GoogleServicesFramework.apk from the file.
7. Mount the Galaxy Tab to your computer via USB cable and copy the com.amarket.apk and GoogleServicesFramework.apk files over to the device.
8. Open Root Explorer. From the sdcard folder, tap GoogleServicesFramework.apk and walk through the installation.
9. From the sdcard folder, tap and hold the com.amarket.apk file until a menu appears and select Copy.
10. Navigate to the \system\app folder and Paste the file into that folder.
11. Tap and hold the com.amarket.apk file and select Permissions.
12. Set permissions to rw-r–r–.
13. Tap com.amarket.apk to install it.
14. Restart the Galaxy Tab and Android Market will be installed and ready to use..
