Coding out of the Box
adb
I have decompile APK using ‘apktool d demoapp.apk’ then compiling apk using ‘apktool b demoapp.apk’ but at compile time it throws error
brut.androlib.AndrolibException: brut.common.BrutException: could not exec (exit code = 1):
Here No resource identifier found for attribute ‘preserveLegacyExternalStorage’ in package ‘android’ and same for ‘requestLegacyExternalStorage’ as well.
I have an Android(7) phone and a Linux pc. By enabling USB debugging and using the terminal of my pc, I am able to read the notifications of my phone using the command: adb shell dumpsys notification --noredact
Now, there are some notifications in android in which we can interact with the app directly from the notification. For example, in a Whatsapp notification, there are usually two buttons: Reply & Mark as read. In YouTube, there are options like Play, Turn off, Watch later. In the output of the above command, these options are visible in the following form:
actions={
[0] "Reply" -> PendingIntent{6becf48: PendingIntentRecord{87b8050 com.whatsapp startService (whitelist: +30s0ms)}}
[1] "Mark as read" -> PendingIntent{c1661e1: PendingIntentRecord{b8e3249 com.whatsapp startService (whitelist: +30s0ms)}}
}
I have two questions:
adb shell <SOME COMMAND> 'Message to be sent in whatsapp with reply option' which will send the text as a reply in whatsapp without opening the app?
adb shell input swipe x0 y0 x1 y1, it requires to unlock the phone each time)
Thank you in advance!
Edit:
Here is what I found that may be relevant to this question.
I think that I have to somehow launch the specific intent linked to the mentioned PendingIntent id (in this case 6becf48 or 87b8050)
Using tthe command adb shell dumpsys activity intents > output.txt and then searching for 87b8050 in output.txt, I found the name of the intent. It was as follows:
* PendingIntentRecord{87b8050 com.whatsapp startService (whitelist: +30s0ms)}
uid=10104 packageName=com.whatsapp type=startService flags=0x0
requestIntent=act=com.whatsapp.intent.action.DIRECT_REPLY_FROM_MESSAGE dat=content://com.whatsapp.provider.contact/contacts/2256 cmp=com.whatsapp/.notification.DirectReplyService (has extras)
whitelistDuration=+30s0ms
Now I think that it may be possible to launch the intent com.whatsapp.intent.action.DIRECT_REPLY_FROM_MESSAGE using adb shell am command, and passing the intent id and message as some parameters.
(Just like we can launch Whatsapp from adb with am command, it should be possible to launch the pendingIntent also.)
My device’s rear (main) camera is broken.
WhatsApp Web pairing uses the main camera in order to scan a QR code and can’t be switched to the front (selfie) one.
Is there any ADB command that can switch the roles of Main and Front cameras? this way, the front will be activated by WhatsApp and I’ll be able to scan the QR code.
Alternatively is there an ADB command that disables the main camera altogether? since that might also do the trick.
I’m with Android 10 with latest security updates (Android One).
I’m searching for a way to set the BSSID my OnePlus One (running LineageOS 16) is connecting to. I started adb shell as root and tried to change the BSSID in /data/misc/wifi/WifiConfigStore.xml, but when restarting the WiFi connection, the *.xml file gets set to default.
Can someone tell me which file needs to be edited that the MAC Address of the BSSID may get written to the *.xml file, or in which format the change needs to be made so that it won’t get set to default?
EDIT:
I found a configuration documentation which tells about editing a Public String, but I don’t know what needs to be edited and how. https://developer.android.com/reference/android/net/wifi/WifiConfiguration#BSSID
Thanks in advance,
Recently I noticed I have opera browser installed. I definitely did not install it because I was sleeping at that time. I checked installation time and revealed it was the day before yesterday
Checking installation source like this outputs android:
adb shell dumpsys package com.opera.browser | grep -e "installerPackageName"
so I don’t know whether it was through Play Store or through APK.
Can I found out who have done this and how can I prevent future intrusions?
P.S. I have MIUI 11.0.3 Global device

I have an application for which I’d like to transfer the app data from my physical device to an emulator on my PC. *The data consists of a single .sol file which is saved at:
datadatapackage.namefilesfile.sol
I’m not proficient with ADB / Linux / Bash, so I’d appreciate any efforts spared to elaborate with more verbose guidance (I’m not afraid to read through essays, I’m afraid of the one-line answers). The device has to be kept stock (rootless). Here are the specs:
Device (Source):
Samsung SM-N950U Stock (T-MO)
Android 8.0
*Bootloader Version: N950USQS5CRL1
Emulator (Destination):
Runtime Environment: 6.0.6 Good
Device Model: Samsung Galaxy Note 8 Android 5.1.1 (US)
After quite a bit of digging around, I finally got ADB backup to work do something (after an OTA update, it kept producing a 1KB file with no error echoed back). I’m not 100% sure the backup is now fully functional, but it now produces a 17KB .ab file (I am using the -noapk argument, and the contents of the backup should decompress into a .sol file so it wouldn’t be a huge file or anything). Here’s the syntax I used:
adb -d backup com.example.example "-noapk -obb -shared" -f examplebackup.ab
When using ADB restore to the emulator, everything goes smoothly and no error message is produced (unlock dialogue prompt comes up so I know it’s going to the correct device). However, opening the application it acts like I’ve just opened it for the first time, so no save data was transferred over. For reference, this is the syntax I used:
adb -s 127.0.0.1:21513 restore examplebackup.ab
I know there are several similar threads, but none addressed this type of cross platform transfer that I saw, and none of the potential workarounds or solutions seemed to work (although one of them did help me figure out the 1KB backup issue). Hoping to get some help with this, and my apologies if this was addressed somewhere but I just couldn’t understand it.
Thanks in advance for any assistance!
In the past weeks, I’ve pieced together more information from here and there, and I’ve decided to come back and update this post for any others who might be struggling with the same issue. At this time, I believe it will not be possible to accomplish my objective of retrieving my data, but it’s not necessarily true for others. Below, I’ll explain my attempts and the setbacks I encountered from a layman’s perspective, but if anyone more knowledgeable on the subject feels inclined to clarify anything I’m unaware of or misunderstood, it’d be greatly appreciated.
