adb shell dumpsys meminfo

The adb shell dumpsys meminfo command is used to obtain detailed information about the memory usage of processes on an Android device. This command provides information about the memory consumed by various processes, including native and Java heap sizes, memory allocations, and more.

Here’s an example of how you can use it:

$ adb shell dumpsys meminfo

When you run this command, it will output a lot of information, including details about the memory usage for each process running on the device.

If you want to focus on a specific package, you can include the package name as an argument:

$ adb shell dumpsys meminfo com.example.myapp

Replace com.example.myapp with the package name of the specific app you are interested in.

The output includes information about various memory-related metrics such as Pss (Proportional Set Size), USS (Unique Set Size), Heap sizes, memory allocations, and more. It’s a valuable tool for developers to analyze the memory usage of their applications.

As with other dumpsys commands, you can redirect the output to a file for easier analysis:

$ adb shell dumpsys meminfo > meminfo_dump.txt

This will save the output to a file named meminfo_dump.txt in the current directory.

Always refer to the official Android documentation for the specific details and interpretation of the output from dumpsys meminfo. Understanding the memory usage of your Android applications is crucial for optimizing performance and avoiding memory-related issues.
