Try to allow installation from unknown sources.

Not working,Erel...
My manifest if it helps :

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="14" />

<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"    />)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.
 SetActivityAttribute(main,  android:windowSoftInputMode, "stateHidden|adjustPan")
 AddPermission("android.permission.READ_CONTACTS")
AddPermission("android.permission.WRITE_CONTACTS") 'if write access is required

android:minSdkVersion="16" android:targetSdkVersion="14"

minimum api 16 but targetting 14? Try to set the second to 22

AddManifestText(
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />

Try to disable the verification step under development options.

It worked for android 5 (probably the manifest editin from DonManfred worked ! thanks !)

in android 4 same errors
Erel I did (just putting the procedure to open adb shell for everyone maybe don't know how) :

• Using Windows Explorer, navigate to your SDK-directory and open the folder "platform-tools",
• If you installed Android Studio Bundle, the default path is: C:\Users\'username'\AppData\Local\Android\sdk
• Hold down the left "Shift"-button while right clicking somewhere inside the folder,
• In the menu, click "Open command window here",
• In the opened command window, type "adb shell" (without the "") and press enter ,
• "shell@grouper:/ $" should now appear on a new line,
• You have now opened your ADB Shell,
• settings put global package_verifier_enable 0

• (in the phone ,but was already deselected) Settings -> Security -> Deselect Verify Apps.

Finally I copied the apk with the usb cable from my pc ,and then opened and installed it from inside the phone with a file browser..works OK !
Maybe this helps to find the problem anyway,to help others.
