How should I get $? of adb shell <command>?
I would like to check the result of adb shell mkdir /xxx.
I executed mkdir command by adb shell and failed but the result of $? is 0.
$ adb shell mkdir /xxx
mkdir failed for /xxx, Read-only file system
$ adb shell echo $?
0
$ adb shell "mkdir /xxx; echo $?"
mkdir failed for /xxx, Read-only file system
0
I would like to get the result code of adb shell <command> but not in the interactive mode like below:
$ adb shell
shell#android:/ $ mkdir /xxx
mkdir failed for /xxx, Read-only file system
255|shell#android:/ $ echo $?
255
You should do:
$ adb shell 'mkdir /xxx; echo $?'
mkdir failed for /xxx, Read-only file system
255
Notice the single quotes, otherwise $? is evaluated before reaching adb.
If you are using an older emulator, then adb shell does not return the exit value. Then you have to use adb shell 'false; echo $?' like in https://stackoverflow.com/a/17480194/306864
In newer emulators, it works properly, then you can do adb shell false || echo failed. Here's how I tested:
$ adb -e android-22 shell false; echo $?
0
$ adb -e android-22 shell 'false; echo $?'
1
$ adb -e android-29 shell false; echo $?
1
$ adb -e android-29 shell 'false; echo $?'
1

Given below is my pipeline yml
# Android

steps:

# Install AVD files
echo "y" | $ANDROID_HOME/tools/bin/sdkmanager --install 'system-images;android-19;google_apis;x86'
echo "AVD system-image successfully downloaded and installed."

- bash: |
# Create emulator
echo "no" | $ANDROID_HOME/tools/bin/avdmanager create avd -n xamarin_android_emulator -k 'system-images;android-19;google_apis;x86' --force
$ANDROID_HOME/emulator/emulator -list-avds

- bash: |
# Start emulator in background
nohup $ANDROID_HOME/emulator/emulator -avd xamarin_android_emulator -no-snapshot > /dev/null 2>&1 &

echo "Emulator started"
displayName: 'Start emulator'
- bash: |
./gradlew testdevelopDebug connectedMockDebugAndroidTest --stacktrace --no-daemon
./gradlew --stop

This works perfect when I use android-28 instead of android-19
Is there any change that I need to make in my pipeline such that I can launch the emulator?
Any help is much appreciated
The adb call in yml was done to get the status and check that locally. In the yml I was trying to pass the while loop into adb.
This example depicts the right usage and solution:
https://stackoverflow.com/a/38896494/
while [ "`adb shell getprop sys.boot_completed | tr -d '\r' `" != "1" ] ; do sleep 1; done
I've read related question
However, I'm using the 'androidx.test:orchestrator:1.4.0', which should not has the bug below 1.2.0.
My case is, I will get error: com.android.build.gradle.internal.testing.ConnectedDevice > No tests found.[GM1910 - 11] FAILED if I enable :
testOptions {
execution 'ANDROIDX_TEST_ORCHESTRATOR'
}
I've done the prefix operations:
$ curl -O https://dl.google.com/android/maven2/androidx/test/orchestrator/1.4.0/orchestrator-1.4.0.apk
$ curl -O https://dl.google.com/android/maven2/androidx/test/services/test-services/1.4.0/test-services-1.4.0.apk
$ adb install -r orchestrator-1.4.0.apk
$ adb install -r test-services-1.4.0.apk
$ adb shell 'CLASSPATH=$(pm path androidx.test.services) app_process / \
androidx.test.services.shellexecutor.ShellMain am instrument -w -e \
targetInstrumentation com.example.notroid/androidx.test.runner.AndroidJUnitRunner \
androidx.test.orchestrator/.AndroidTestOrchestrator'
Time: 0
OK (0 tests)
My ADB command is,
adb shell am instrument -w -r -e debug false -e class com.example.deepak.myapplication.ExampleInstrumentedTest com.example.deepak.myapplication.test/android.support.test.runner.AndroidJUnitRunner
I'm trying to fix a bash script. The part of relevance is this one:
function do_get_apks {(
mkdir -p apks
cd apks
adb shell pm list packages > installed_packages
adb shell pm list packages -3 > installed_packages_user
while read p; do
# remove trailing 'package'
package=$(echo "${p/package:/}" | tr -d '\r\n')
mkdir "$package"
echo "$package"
echo "adb shell pm path $package"
apkpath=$(adb shell pm path "$package")
echo "$apkpath"
apkpath1=$(echo "$apkpath" | grep "package")
echo "$apkpath1"
apkpath2=$(echo "$apkpath" | grep "package" | tr -d '[[:space:]]')
echo "$apkpath2"
apkpath=$(adb shell pm path "$package" | grep package | tr -d '[[:space:]]')
adb pull ${apkpath/package:/} "$package/"
adb shell dumpsys package "$package" > "$package"/info
done < installed_packages)}
Thing is there are incongruities between the output of the command echo "adb shell pm path $package" where package is com.mobeam.barcodeService which returns a list of all the packages, and the actual content of the command "adb shell pm path com.mobeam.barcodeService", which returns just package:/system/app/BeamService/BeamService.apk (which is the desired output)
It looks like the script is returning a list of packages instead of the desired one. You can test this script with adb and any Android Device.
EDIT: Just to clarify, the error I'm getting is the following one:
adb: error: SendRequest failed: path too long: 3922
adb: error: failed to stat remote object

Manually, we can run:
adb shell
su
chmod 666 /dev/graphics/fb0
export CLASSPATH=/data/local/device.jar
export LD_LIBRARY_PATH=/data/local
exec app_process /system/bin com.device.client.Main /data/local/device.conf &
However, we need to be able to run that from a bash script on the computer compiling the program.
I have tried:
adb shell "su
&& chmod 666 /dev/graphics/fb0
&& export CLASSPATH=/data/local/device.jar
&& export LD_LIBRARY_PATH=/data/local
&& exec app_process /system/bin com.device.client.Main /data/local/device.conf &"
But since we are entering the su shell, this does not work.
Can you please suggest a solution?
Try this:
adb shell "su -c '
chmod 666 /dev/graphics/fb0
&& export CLASSPATH=/data/local/device.jar
&& export LD_LIBRARY_PATH=/data/local
&& exec app_process /system/bin com.device.client.Main
/data/local/device.conf &'"
It might be possible to simplify it, too:
adb shell "su -c '
chmod 666 /dev/graphics/fb0 &&
CLASSPATH=/data/local/device.jar
LD_LIBRARY_PATH=/data/local
app_process /system/bin com.device.client.Main
/data/local/device.conf &'"
This is because you can set environment variables for one job just by prepending them on the line, rather than the export this, export that form.
