Intent case (system BUG) caused by "OPEN" after Android software is installed)

There are many entry points for opening a program:

 

Run the shell command line;

Launcher standby interface execution;

The status notification bar is running;

Desktop Shortcut running;

Call and run in software;

 

Run "open" after installing the software!

 

The code for calling the program is as follows (see COM. Android. launcher/. launcher. Java ):

 

Intent intent = new Intent (this, TestActivity. class); <br/> intent. setAction (Intent. ACTION_MAIN); <br/> intent. addCategory (Intent. CATEGORY_LAUNCHER); <br/> intent. addFlags (Intent. FLAG_ACTIVITY_NEW_TASK); <br/> intent. addFlags (Intent. FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); <br/> this. startActivity (intent ); 

 

After installing the software, click "open" to call the code as follows (see COM. Android. packageinstaller/. installappdone. Java ):

 

Intent intent = new Intent (this, TestActivity. class); <br/> this. startActivity (intent ); 

 

If you execute "open" immediately after installing the software, run the program, press the Home Key to return to the background, and then run the program in several other ways, then another main program will be started. This is because the intent processing mechanism is: Compare activity first, then compare action, flag, bnds ..., the two methods have different actions. One has a launcher action and the other does not. Therefore, they are considered to start two different intents.

 

Currently, only one simple processing method is available:

 

Main Program: splashactivity. Java

Original program entry program: loginactivity. Java

 

After the program is started, add a quick notification in the status notification bar. The Code is as follows:

Test process:

 

A. install the software locally;

B. Run "open" after installation ";

C. The running software adds noticification testactivity from splashactivity;

D. Jump to splashactivity (with launcher action );

E. Jump to testactivity;

F. click the button to jump to test2activity;

G. In the drop-down notification bar, click program notification to run the program normally.

 

Todo: after the software is installed and the open command is executed, the program will still start two identical activities from the standby interface. This problem is not solved! :(
