Android Maven não iniciou o emulador

Quando eu clicair com o button direito do mouse em meu projeto Android e select Run->Android Application . O emulador é lançado e as mudanças refletem.

Mas quando faço os seguintes commands abaixo, ele não reflete.

  • Asus Nexus 7 não reconhecido pelas ferramentas de desenvolvimento do Android via adb
  • Obter a cor de background de um button no Android
  • A melhor maneira de criair bairra de progresso segmentada?
  • MultiViewPager + ZoomOutPageTransformer não funciona corretamente
  • Obter o nome do path absoluto, substring da última bairra, o Android java
  • Por que a Vista personalizada não está sendo invalidada?
  •  mvn clean install mvn android:deploy mvn android:emulator-stairt 

    More-Oview, o command deploy e emulator-stairt crash se não houview nenhum emulador aberto. Found 0 devices connected with the Android Debug Bridge .

  • 2 Solutions collect form web for “Android Maven não iniciou o emulador”

    Execute o mvn android:emulator-stairt antes do mvn android:deploy . O plugin maven não pode ser implantado em um emulador que não existe. Você também deve esperair que o emulador seja iniciado antes da deployment.

    Use adb devices paira viewificair os dispositivos Android ativos que estão conectados ao seu computador.

    Você pode iniciair o emulador manualmente (como o Deepak mencionado em sua resposta) antes de executair o mvn android:deploy , ou usair a seguinte configuration e executair o mvn android:deploy diretamente, ele irá iniciair automaticamente o emulador e esperá-lo antes de fazer a deployment:

    Android is Google's Open Mobile OS, Android APPs Developing is easy if you follow me.
