Open app by package name

[Ger PG]

Hello,

I am trying to open an app whose package name is stored in a variable. For example, the variable is %Player and it contains "com.soundcloud.android". I have tried the shell command "am start -m "Player" but nothing happens (both with and without using root).

What am I doing wrong?

Thank you very much in advance.

You can get the app name from the package name via Java:

Test (69)
A1: Java Function [ Return:(PackageManager) pacman Class Or Object:CONTEXT Function:getPackageManager
{PackageManager} () Param: Param: Param: Param: Param: Param: Param: ]
A2: Java Function [ Return:app_info Class Or Object:pacman Function:getApplicationInfo
{ApplicationInfo} (String, int) Param:net.dinglisch.android.taskerm Param:0 Param: Param: Param: Param: Param: ]
A3: Java Function [ Return:%label Class Or Object:app_info Function:loadLabel
{CharSequence} (PackageManager) Param:pacman Param: Param: Param: Param: Param: Param: ]
A4: Flash [ Text:%label Long:Off ]

Hi! Thanks for your reply. In fact, I already know the package name, the only thing I want is to open it.

Sorry, totally misread that. To launch an app using its package name:

Test (69)
A1: Java Function [ Return:(PackageManager) pacman Class Or Object:CONTEXT Function:getPackageManager
{PackageManager} () Param: Param: Param: Param: Param: Param: Param: ]

A2: Java Function [ Return:intent Class Or Object:pacman Function:getLaunchIntentForPackage
{Intent} (String) Param:uk.co.aifactory.chess Param: Param: Param: Param: Param: Param: ]
A3: Java Function [ Return: Class Or Object:CONTEXT Function:startActivity
{} (Intent) Param:intent Param: Param: Param: Param: Param: Param: ]

No root needed :)

Great!

I was interested in this topic to launch an app with the package name only.

Thanks, Robert.

And I have a question, too.

Is there a way to know the package name (and class name) of the front app with java?

[Robert Ryan]

If you know the label of the top app, i.e. "Tasker" or "Chess", it can be done. It's  bit more complicated than the previous examples:

Test (69)
A1: Variable Set [ Name:%app_name To:Tasker Do Maths:Off Append:Off ]
A2: Variable Set [ Name:%package_name To:Not Found Do Maths:Off Append:Off ]
A3: Java Function [ Return:(PackageManager) pacman Class Or Object:CONTEXT Function:getPackageManager

{PackageManager} () Param: Param: Param: Param: Param: Param: Param: ]

A4: Java Function [ Return:app_list Class Or Object:pacman Function:getInstalledApplications
{List} (int) Param:128 Param: Param: Param: Param: Param: Param: ]
A5: Java Function [ Return:list_iterator Class Or Object:app_list Function:iterator
{Iterator} () Param: Param: Param: Param: Param: Param: Param: ]
A6: Java Function [ Return:%has_next Class Or Object:list_iterator Function:hasNext
{boolean} () Param: Param: Param: Param: Param: Param: Param: ]
<Find>
A7: Goto [ Type:Action Label Number:1 Label:End Find ] If [ %package_name !~ not found | %has_next !~ true ]
A8: Java Function [ Return:(ApplicationInfo) app_info Class Or Object:list_iterator Function:next
{Object} () Param: Param: Param: Param: Param: Param: Param: ]
A9: Java Function [ Return:%label Class Or Object:app_info Function:loadLabel
{CharSequence} (PackageManager) Param:pacman Param: Param: Param: Param: Param: Param: ]
A10: If [ %label ~ %app_name ]
A11: Java Function [ Return:cls Class Or Object:app_info Function:getClass
{Class} () Param: Param: Param: Param: Param: Param: Param: ]
A12: Java Function [ Return:fld Class Or Object:cls Function:getField
{java.lang.reflect.Field} (String) Param:processName Param: Param: Param: Param: Param: Param: ]
A13: Java Function [ Return:%package_name Class Or Object:fld Function:get
{Object} (Object) Param:app_info Param: Param: Param: Param: Param: Param: ]
A14: End If
A15: Goto [ Type:Action Label Number:1 Label:Find ]
<End Find>
A16: Anchor
A17: Flash [ Text:%package_name Long:Off ]

[Jay K]

Oh! There is a way.

Thanks again, Robert. It shows the package name correctly. Great!!!

[Robert Ryan]

Sorry, there is a bug in that. I should have updated %has_next before the last goto:

Test (69)
A1: Variable Set [ Name:%app_name To:AnalyzeThis Do Maths:Off Append:Off ]

A2: Variable Set [ Name:%package_name To:Not Found Do Maths:Off Append:Off ]
A3: Java Function [ Return:(PackageManager) pacman Class Or Object:CONTEXT Function:getPackageManager
{PackageManager} () Param: Param: Param: Param: Param: Param: Param: ]
A4: Java Function [ Return:app_list Class Or Object:pacman Function:getInstalledApplications
{List} (int) Param:128 Param: Param: Param: Param: Param: Param: ]
A5: Java Function [ Return:list_iterator Class Or Object:app_list Function:iterator
{Iterator} () Param: Param: Param: Param: Param: Param: Param: ]
A6: Java Function [ Return:%has_next Class Or Object:list_iterator Function:hasNext
{boolean} () Param: Param: Param: Param: Param: Param: Param: ]
<Find>
A7: Goto [ Type:Action Label Number:1 Label:End Find ] If [ %package_name !~ not found | %has_next !~ true ]
A8: Java Function [ Return:(ApplicationInfo) app_info Class Or Object:list_iterator Function:next
{Object} () Param: Param: Param: Param: Param: Param: Param: ]
A9: Java Function [ Return:%label Class Or Object:app_info Function:loadLabel
{CharSequence} (PackageManager) Param:pacman Param: Param: Param: Param: Param: Param: ]
A10: If [ %label ~ %app_name ]
A11: Java Function [ Return:cls Class Or Object:app_info Function:getClass
{Class} () Param: Param: Param: Param: Param: Param: Param: ]
A12: Java Function [ Return:fld Class Or Object:cls Function:getField
{java.lang.reflect.Field} (String) Param:processName Param: Param: Param: Param: Param: Param: ]
A13: Java Function [ Return:%package_name Class Or Object:fld Function:get
{Object} (Object) Param:app_info Param: Param: Param: Param: Param: Param: ]
A14: End If

A15: Java Function [ Return:%has_next Class Or Object:list_iterator Function:hasNext

{boolean} () Param: Param: Param: Param: Param: Param: Param: ]

A16: Goto [ Type:Action Label Number:1 Label:Find ]
<End Find>
A17: Anchor
A18: Flash [ Text:%package_name Long:Off ]

[Jay K]

That's OK, Robert.

I already caught the problem and solve it by moving the label 'Find' to A6.

Thanks for your kindness. :-)

I used your method to get the label name into a Tasker menu but would like to know if you could help me get the labels for all the apps (apps = those that would appear in the Application Selection window if you add new profile in Tasker and tapped Application) and stored them in a variable array that can be used as the source for the Menu?

I could really use your help and would appreciate beyond what words could express! I opened a thread on Reddit (link below) which came up a little short in terms of populating the menu  but in essence I'm trying to have an app list menu pop up on long tap of a shortcut within a scene and store the user selection as the default target for said shortcut. It can be done using AutoLaunch, a non-free 3rd party dependency, which I'd prefer not to have to use.
