Just came around the “See all apps with this permission” link while tuning app permissions

Checking Android phone location
Maybe the easiest way is sign into Google and search android location.
I was lazy to check the phone’s battery level so I checked via https://www.google.sk/android/find 😀
Read SMS via Mi cloud
Thumbs up for Mi Cloud (Xiaomi) because the ability to read synced SMS messages.
Network connection speed in status bar on Android
Don’t know if it’s a new Android feature or Xiaomi improvement, but I definitely like network connection speed in the status bar.
If you don’t have it in the Notifications settings menu
than you could use an app for that, e.g. https://play.google.com/store/apps/details?id=com.internet.speed.meter.lite
Automating Android auto-sync toggle while charging
My older Nexus tablet is slow when toggling WiFi so I disabled accounts auto-sync, but needed a solution to auto enable when charging.
So I found an automation app Automate and made a flow for it.
Auto access Android files via MTP filesystem
Finally figured out Android file access via MTP using autofs and jmptfs
# /etc/autofs/auto.misc android -fstype=fuse,allow_other,umask=000 :jmtpfs
To test:
$ sudo systemctl stop autofs.service $ sudo automount -vf Starting automounter version 5.1.1, master map auto.master using kernel protocol version 5.02 lookup(file): failed to read included master map auto.master mounted indirect on /misc with timeout 300, freq 75 seconds ghosting enabled
After listing
$ ls /misc/android 'Internal storage'
the following output should appear
attempting to mount entry /misc/android >> Device 0 (VID=18d1 and PID=4e41) is a Google Inc (for Asus) Nexus 7 (MTP). mounted /misc/android
Android full backup with adb
To download Anroid SDK go to https://developer.android.com/sdk/index.html
The backup command
mike@mikembp:~/Downloads/android/sdk/platform-tools$ ./adb backup -all Now unlock your device and confirm the backup operation.
Default backup file name is backup.ab
mike@mikembp:~/Downloads/android/sdk/platform-tools$ ls -la backup.ab -rw-r----- 1 mike wheel 60M Feb 9 07:39 backup.ab
Get some log stuff to examine phone stat data
mike@mikembp:~/Downloads/android/sdk/platform-tools$ ./adb logcat -b radio -d > radio.logcat mike@mikembp:~/Downloads/android/sdk/platform-tools$ ./adb logcat -d > adb.logcat
Rooting an Android Samsung Galaxy Advance S GT-I9070
Today I googled my Androids firmware build code I9070XXLQG and read http://www.ibtimes.co.uk/galaxy-s-advance-root-i9070xxlqg-android412-jellybean-485079.
I have Android 4.1.2 Jelly Bean official update on my smartphone, which I updated with Samsung’s Kies over USB cable.
From curiosity I downloaded the rooting package http://d-h.st/ook and looked at root/META-INF/com/google/android/updater-script
In a nutshell, rooting is adding su (SuperUser) binary into /system/bin.
ui_print("***************************");
ui_print("Rooting with SuperSU 0.95 & Busybox 1.20.2");
ui_print("***************************");
show_progress(1.000000, 0);
ui_print("Installing temporary busybox");
package_extract_file("system/xbin/busybox", "/tmp/busybox");
set_perm(0, 0, 0777, "/tmp/busybox");
set_progress(0.200000);
ui_print("Mounting system...");
run_program("/tmp/busybox", "mount", "/system");
set_progress(0.300000);
ui_print("Removing old superuser");
delete("/system/bin/su");
delete("/system/xbin/su");
delete("/system/app/superuser.apk");
delete("/system/app/superUser.apk");
delete("/system/app/Superuser.apk");
delete("/system/app/SuperUser.apk");
set_progress(0.400000);
ui_print("Installing Superuser & Busybox...");
package_extract_dir("system", "/system");
set_progress(0.600000);
ui_print("Setting Permission...");
set_perm(0, 0, 06755, "/system/xbin/su");
set_perm(0, 0, 0644, "/system/app/superuser.apk");
set_perm(0, 0, 04755, "/system/xbin/busybox");
set_progress(0.700000);
ui_print("Installing Busybox...");
run_program("/system/xbin/busybox", "--install", "-s", "/system/xbin");
set_progress(0.900000);
ui_print("Symlinking...");
symlink("/system/xbin/su", "/system/bin/su");
ui_print("Unmounting system...");
run_program("/tmp/busybox", "umount", "/system");
ui_print("Deleting temporary busybox");
delete("/tmp/busybox");
set_progress(1.000000);
show_progress(1.000000, 0);
ui_print("Root complete!");
ui_print("SuperSU 0.95 & Busybox 1.20.2");
After reading and playing around with adb I decided that I go for it
For strengthening my decision a checked if the MD5 matches and it matched
mike@mikembp:~/Downloads/android$ md5 root.zip
MD5 (root.zip) = 3d5cc207f625a032e7ff4fe92e3e6efa
