Finally, if you rely on these apps for too long, then you may be suddenly surprised to see them stop working when Android O rolls out because the next Android version is killing the ability of these apps to draw on top of System UI elements. Furthermore, many of these apps require you to enable an Accessibility Service to monitor apps to know when to re-color the nav bar, which may reduce performance. And they do work – however, many users report that these apps are buggy in certain apps like Chrome, when playing full screen video, or some games. Now, the following section may not seem like a huge deal due to the fact that there are numerous applications on the Play Store that promise to change your navigation bar without root. We’ll take advantage of this fact in the next section, where we show you how to change the icons on the nav bar buttons. Right-justified: adb shell settings put secure sysui_nav_bar "space,space,recent home back"īut we can also change the nav bar buttons to be something entirely different than the standard back, home, or recent keys, such as sending one of the many KeyEvents. Left-justified: adb shell settings put secure sysui_nav_bar "recent home back,space,space" We can, for instance, make our flipped nav bar keys left-justified or right-justified by changing where the two spaces are placed:
We can move the keys around however we want by modifying the string value of the preference. Hence, the command we would send to swap the recent and back keys would look like this adb shell settings put secure sysui_nav_bar "space,recent home back,space"Īs you might guess, this is fairly flexible.
Now, in order to actually modify this string, we need to use the ADB shell command with this syntax adb shell settings put secure sysui_nav_bar "STRING" Import 7.widget.Note: if you are attempting to enter any of the following commands from a rooted shell environment such as Terminal Emulator on your phone, then you will need to omit “adb shell” from the commands before sending them. Step 3 − Add the following code to src/MainActivity.java import Step 2 − Add the following code to res/layout/activity_main.xml. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
