Debug at the beginning of the program running. startMethodTracing ("yourActivityTrace"); then call Debug in onPause. stopMethodTracing (); why do you want to write the end in onPause () instead of onStop ()? If you look at the api, you will see that the Api introduces onPause () it will be triggered after you return and click the home button, while onStop () is generally triggered by the system. When the program is in the background, and when the memory is tight, it may be called, but it may ne
