We need to be able to turn on/off screen.

When you follow Mobly-101 tutorial and run the following command:
python3 hello_world_test.py -c sample_config.yml
You see following error:

If you following this Mobly discussion, it resolves by adding the following to build.gradle:
implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.10'

Regarding contribution guidelines

I didn't update any of these files, but running ./gradlew presubmit gives me Not all files were formatted.
Checkout out the scan results here.

Do let me know if you need anything else.

Thanks!

Hello, i tried to write a test class for a specific snippet, but i cannot make it work.
Any suggestion?

import androidx.test.filters.SmallTest;
import androidx.test.runner.AndroidJUnit4;

import org.junit.Test;
import org.junit.runner.RunWith;

@SmallTest
@RunWith(AndroidJUnit4.class)
public class DemoTest {

    @Test
    public void testAudioSnippet() {
        AudioSnippet audioSnippet = new AudioSnippet();
        audioSnippet.getMusicMaxVolume();
    }
}

And here is the output when i run test case

Testing started at 12:46 PM ...

I am executing this ./gradlew examples:ex2_espresso:assembleDebug examples:ex4_uiautomator:assembleDebug but again and again getting error. I have already downloaded android version 24,27,28,29. Also set the path in sdk.dir of local.properties. But still getting error.

Suggestion to publish as an android library, instead of building an application.

Apps could use this and mobly-snippet-lib in their own codebase in an artifact published to maven central.

These Rpcs don't work. A more reliable adb cmd exists. So we don't need them in MBS.

Like making a call.

In the instructions, ./build/outputs/apk/mobly-bundled-snippets-debug.apk is now ./build/outputs/apk/debug/mobly-bundled-snippets-debug.apk due to gradle updates

I was trying to test two devices simultaneously but got confused because the shell only allow me to connect to one device. Could you please add more explanation about how to test multiple devices?

Will you accept PRs for new snippets in Kotlin? or just Java?

Right now the accounts added by AccountSnippet.addAccount will automatically stop any attempt to sync the added account.
We shall find a way to allow syncing of added accounts in a reliable way.

"Error:Conflict with dependency 'com.google.errorprone:error_prone_annotations' in project 'mobly-bundled-snippets'. Resolved versions for app (2.0.18) and test app (2.0.19) differ. See http://g.co/androidstudio/app-test-app-conflict for details."

Adding this seems to work around it:
compile 'com.google.errorprone:error_prone_annotations:2.0.19'

Not sure what's going on

When I tried to build the ToT project following the instructions, I got:

$ ./gradlew assembleDebug
...
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'mobly-bundled-snippets'.
> Could not resolve all dependencies for configuration ':_debugApkCopy'.
   > Could not find com.google.android.mobly:snippetlib:0.0.1.
     Required by:
         :mobly-bundled-snippets:unspecified

Could use a generic method to open a socket to an external site that can used instead of curl. This should be easy enough and will eliminate the need for curl on the device.

Should we be using this to gate some actions?

Since Android M the behavior of BluetoothAdapter.getAddress() is broken and will always return 00:02:00:00:00 as Bluetooth adapter hardware address.

While executing BT sample test with multiple devices, BT discovery fails with require ADMIN permissions though AndroidManifest.xml already has configured for the required BT settings and also on the devices MultiDexApplication is give permission for all the requested permissions.

Manfiest File BT Permissions entries :

    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />

We should be able to initiate pairing with a device and connecting to it.

We should probably synchronize all the Rpc methods unless there's a valid use case for one to be not synchronized.

Currently the BluetoothAdapterSnippet only has enable/disable APIs.
We need to add more functionalities like the following:

• Make self discoverable
• Conduct a discover and find nearby discoverable devices
• Pair with another device
• Connect to another device
• List paired devices
• List connected devices

Hello, when I am tring to run "snippet_shell.py com.google.android.mobly.snippet.bundled" by following the instructions, I met error below:
pkg_resources.ResolutionError: Script 'scripts/snippet_shell.py' not found in metadata at '/usr/local/lib/python3.7/site-packages/mobly-1.9.1.dist-info'

What can I fix this problem?

Thanks,
Wolfgao

Add an rpc that makes a toast on the screen. This serves as an easy way to make sure the bundled snippet functions.

Saves a lot of typing from bluetooth, also makes it more consistent with the prefix ble for BLE snippet class

With this PR #158, there is a question "What are the breakages from bumping the targetSDK?"

It would be good to have a pattern for new snippets at least, to demonstrate that the snippet works on some particular device.

Useful when

• changing the code of the snippet
• changing the build such as targetSdk
• testing against some new device

When using btPairDevice(), the PairingBroadcastReceiver (automatic pairing confirmation) is only registered for the device from which the paring request is started. However, since the corresponding confirmation, for successful pairing must be confirmed on both devices, the PairingBroadcastReceiver must also be registered for the second device.

My solution for this problem was implementing a additional Rpc-function which is only used to register the broadcast receiver for any device as required.

public void btStartPairingBroadcastReceiver () {
    mContext.registerReceiver(new PairingBroadcastReceiver(mContext), PairingBroadcastReceiver.filter);
}

PairingBroadcastReceiver#onReceive
BluetoothA2dpSnippet#onServiceConnected
BluetoothA2dpSnippet#onServiceDisconnected

also an empty @return in docstring of BluetoothAdapterSnippet#getKnownDeviceByAddress

1. Bluetooth is on
2. call btDisable
3. immediately call btEnable

There's a > 30% chance that the call in 3 fails due to timeout.
Looks like Android bluetooth stack is not very good at handling stress calls...

New Feature Request

Can we please add UWB Ranging Snipped into Mobly Bundled Snippets? I would be happy to contribute here.

Hi Like API given in "RPCs provided by BluetoothA2dpSnippet", could you provide the same for HFP profile, MAP and PBAP and Bt clasic as well, like connect, disconnect and isCOnnected

Add support for basic Android Wi-Fi APIs.

How are we using it and is something failing silently?

We should check if the network is already connected/has been added before adding/connecting to it.

From the review thread of #34, we should try dumping all the serialized objects to see if the fields are consistently named, any major info is missing, and see whether it makes sense to capture what they look like in documentation for end users.

Hello,

Currently there is an A2DP snippet, which controls whether media playback(Media audio in BT settings) is connected/disconnected. But in my device BT settings (Samsung Galaxy S9), there is also a setting to connect/disconnect Call audio. Is there a profile that we can use to connect/disconnect all profiles (A2DP & calls) through snippet? That would be very useful.

Right now there are only two fields.
