android - Espresso Instrumentation Tests - how to uninstall or delete the app after the test -

i setup espresso instrumentation framework run android functional automation tests. every test, want login app , delete app after finish test.

so, setup below:

public class firstsampletest extends basetest {

private final basetest basetest; 

// private final elementutils elementutils;

public firstsampletest() throws interruptedexception {     this.basetest = new basetest(); }  @before public void initiate() throws interruptedexception {     //i have setup login method here login app after installs }  @rule public activitytestrule<splashscreenactivity> splashscreenactivityactivitytestrule = new activitytestrule(splashscreenactivity.class);  @test public void testthehomescreen() throws interruptedexception {    //some tests go here.  }  @after public void teardown() throws interruptedexception {     //i want uninstall app or delete emulator once test run  }  } 

uninstalling app instrumentation tests not possible. however, once tests run, app uninstalled automatically.

note: app not uninstalled when single test run. please run whole build using command ./gradlew connectedandroidtest
