編譯我的代碼後,我得到這個異常爲什麼得到這個堆棧跟蹤?
java.lang.IllegalStateException
:沒有註冊的儀器!必須在註冊儀器下運行。
我使用eclipse IDE和ADT插件。
import android.support.test.uiautomator.*;
import android.support.test.InstrumentationRegistry;
import android.support.test.internal.runner.junit3.*;
import android.support.test.internal.runner.listener.InstrumentationResultPrinter;
import android.support.test.rule.*;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import android.os.RemoteException;
import android.support.*;
@RunWith(JUnit4.class)
public class uia {
private UiDevice d;
@Before
public void setup() throws RemoteException {
d = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
d.isScreenOn();
}
@Test
public void home(){
d.pressHome();
}
}
運行此代碼後,我得到了以下跟蹤:

有什麼建議?
爲了幫助,人們需要看到你的代碼。 – BPS
