Android: Allow Installation of Non-Market Apps

   Posted by Lê Hoàng in Android

The Android system by default does not allow users to install applications from unknown sources. However, if you are sure that the application or game setup files are safe, you can enable this ability. This tutorial contains all the necessary steps to activate this feature for Android version 2.2, 2.3, and 4.0.

The tutorial will be divided into 2 parts. The first part is for Android 2.2 and 2.3. The second part is for Android 4.0 (ICS).

Android 2.2 or Android 2.3:

1. Open the app drawer and go to Settings.

2. In the Settings screen, go to Applications.

3. Check the Unknown sources option at the top of the screen. This option will let you install apk files from the device’s storage or from the sd card.

4. When the warning window appears, just tap OK.

Android ICS 4.0.3:

The process of enabling installation from unknown sources on Android 4.0 is different from the older versions. The option is moved to another location. Fortunately, finding and enabling are rather easy.

1. Open the app drawer and go to Settings. Please note that I am using the Go launcher with the default Samsung touchwiz icons. The Settings icon will be different on other phones.

2. When you are in the Settings screen, scroll down to find the Security section and tap on it.

3. Scroll down to the Device administration section and check the Unknown sources option.

4. Tap OK when the warning window appears.

      do you have corporate email installed?
      if so then, that feature has been removed by the administrator

      if not, then the feature has been hidden from your view with the 4.03 update.

      still looking for the answer.

      if you have corporate email then remove corporate email
      check and isntall the app you’re looking for
      then setup corporate email.

      let me know if it works… :)

        Thanks, that was exactly the issue I had, corporate Exchange. I have spent the last 30 minutes trying to figure out why the option wasn’t displaying.

    I don’t knw hw to installed

  • Lianne

    I have the install from unknown sources enabled on my droid 4.0.4 and the “install” button after clicking the .apk just simply does not respond. I also cannot copy the .apk to the system/apk folder, as some instructions suggest. EStrongs file manager reports “copy failed”. What else may be blocking these operations?
