This is the android version of ooniprobe.

Download it on the Play Store.

This application requires Android Studio. In any case, before opening the project with Android Studio, make sure you download the dependencies using the project Makefile. Before you can do this, you should install the GPG key with which binaries are signed. Binaries are digitally signed by Simone Basso using a PGP key with ID 7733D95B and fingerprint (7388 77AA 6C82 9F26 A431 C5F4 80B6 9127 7733 D95B) or by Lorenzo Primiterra using a PGP key with ID ECEB9D12 and fingerprint (1191 0C85 CD8C D493 8DFA 17F7 AA09 A57A ECEB 9D12). You can fetch this key using gpg using the following command:

gpg --recv-keys 7733D95B ECEB9D12

After this step, you can proceed with automatically downloading binaries and verifying their digital signatures using this command:

make unpack

If the signature is correct, the above command will install the JNI libaries inside the src/main/ folder. Specifically, the following paths are affected by that command:

• app/src/main/jniLibs: added with Measurement Kit jniLibs compiled for several Android architectures inside it

• app/src/main/java/org/openobservatory/measurement_kit/jni/: added with Java files corresponding to the jniLibs

All the added files should be recognized by Android Studio.

Building an apk

• Ensure you have Android Studio and gradle installed

On macOS you can do:

brew cask install android-studio

Then you should open the project in Android Studio and click on build.

The built apk will end up inside of app/build/outputs/apk/.

If you wish to test the apk inside of an emulator this can be done with (assuming you have created an emulator named Nexus_5_API_23_marshmallow_6.0):

~/Library/Android/sdk/tools/emulator -avd Nexus_5_API_23_marshmallow_6.0
~/Library/Android/sdk/platform-tools/adb install app/build/outputs/apk/app-debug.apk

The app should then be installed inside of the emulator Nexus_5_API_23_marshmallow_6.0.
