I need to create a Robotium application that would use Settings application to turn ON/OFF WIFi from menu Settings->Wireless & networks->Wi-Fi. I managed to find some sample code here that demonstrates how to launch application by having apk file only. The problem is that my Robotium application should have the same signature with the (system) Settings application. While trying to run application I get the error message:
Test run failed: Permission Denial:
from pid=354, uid=354 not allowed
because package com.jayway.test does
not have a signature matching the
- Can I somehow make it work with the Android Emulator?
- If I compile an Android phone image, how can I use the Android system signature with my application?
I was having the same problem.. There are some permissions that only system apps are allowed to have . I was trying to access the
adb shell dumpsys commands from my application with the permissions
The solution to this is …
In the Android manifest file of your project add the following line in the manifest tag
You need to have two signature keys present in the code that is used to build the binary.
that is present in the
Download a tool from the net i.e.
From the eclipse export your unsigned apk. by right click on the project from the android tools.
Keep all the things i.e. keys , unsigned apk, and signapk.jar in a folder. Run the following Command
java -jar signapk.jar platform.x509.pem platform.pk8 unsigned.apk signed.apk
unsigned apk is the name of your apk and signed apk is the new name you want .
After this just install your signed app in the phone with the command
adb shell install signed.apk
The best way to enable wifi from your application would be to use the WifiManager.
WifiManager wManager = (WifiManager)getSystemService(Context.WIFI_SERVICE); if(!wManager.isWifiEnabled() && wManager.getWifiState() != WifiManager.WIFI_STATE_ENABLING) wManager.setWifiEnabled(true);
Note: You also have to add the following permissions to your manifest
<uses-permission android:name="android.permissions.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permissions.CHANGE_WIFI_STATE" />
