ADB Commands

According to documentation:

Android Debug Bridge (adb) is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.

Link for more info.

3) Check a jobscheduler info using the following command:

adb shell dumpsys jobscheduler

As the output is huge, you should cmd+F or ctrl+f for your package name. It should look like

JOB #u0a93/17: eec3709 com.foo.bar.application/com.evernote.android.job.v21.PlatformJobService
    u0a93 tag=*job*/com.foo.bar.application/com.evernote.android.job.v21.PlatformJobService
    Source: uid=u0a93 user=0 pkg=com.samplejobscheduler.application
    JobInfo:
      Service: com.foo.bar.application/com.evernote.android.job.v21.PlatformJobService
      PERIODIC: interval=+15m0s0ms flex=+5m0s0ms
      PERSISTED
      Requires: charging=false deviceIdle=false
      Network type: 2
      Backoff: policy=1 initial=+30s0ms
      Has early constraint
      Has late constraint
    Required constraints: TIMING_DELAY DEADLINE UNMETERED
    Satisfied constraints: CONNECTIVITY NOT_ROAMING APP_NOT_IDLE DEVICE_NOT_DOZING
    Unsatisfied constraints: TIMING_DELAY DEADLINE UNMETERED
    Earliest run time: 07:23
    Latest run time: 12:23
    Ready: false (job=false pending=false active=false user=true)

As you can see, the requirements set when scheduling the job are included in the output as well as the backoff policy, network etc.
The most important info

Earliest run time: 07:23
Latest run time: 12:23
Ready: false (job=false pending=false active=false user=true)

If you are testing on Android 7.1 and higher, then you can force-run a scheduled job using the following command.

adb shell cmd jobscheduler run -f PACKAGE_NAME JOB_ID

PACKAGE_NAME should be the package of your app.
JOB_ID is set when scheduling a job

Android ADB Commands (Part 2) Alarms

ADB Commands

Previous post: PART I

According to documentation:

Android Debug Bridge (adb) is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.

Link for more info.

2) Check if alarms are set and when they are scheduled to trigger

adb shell dumpsys alarm

The command is extremely verbose, I will recommend to filter with grep such as

adb shell dumpsys alarm | grep com.package.name

Tip 1: If you are not going to use grep or something similar use cmd+F or ctrl+F to find your app by searching the package name.

Tip 2: If your terminal's buffer size is not big enough, and you are not using the grep command, it might better to output into a file.

i.e adb shell dumpsys alarm > AlarmsOutput.txt

The output looks like:

Batch{28b15ce num=18 start=60346095 end=65172917 flgs=0x8}:

    RTC #17: Alarm{ae74957 type 1 when 1491279601728 com.package.name}

      tag=*alarm*:Alarm_Intent

      type=1 whenElapsed=+11h57m57s410ms when=2019-04-04 07:20:01

      window=+8h59m59s997ms repeatInterval=0 count=0 flags=0x0

      operation=PendingIntent{d1cec44: PendingIntentRecord{d3307ba com.package.name broadcastIntent}}

As you can see from above the when= tells us when is set to get triggered.

This is extremely helpful for debugging and verifying AlarmManager's behaviour.

Link for more info.

I will try through a series of posts to go through my favorite commands.

1) Set battery level

adb shell dumpsys battery set level 5

The command above, sets the phone's battery to 5%. This could be used to test how the app behaves with low battery level, or if your dark theme is being enabled etc.

Reset the battery level back to the real one with

adb shell dumpsys battery reset

Part two available now
