过程如下：
1、下载米聊 APK，重新签名，安装到模拟器。
2、简历测试工程导入 robotium jar 包。
3、清单文件如下：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xiaomi.channel.test"
    android:versionCode="1"
    android:versionName="1.0" >
    <instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="com.xiaomi.channel" />
    <uses-sdk android:minSdkVersion="8"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="android.test.runner" />
    </application>
</manifest>

4、用例代码如下：

public Solo solo;
    public Activity activity;
    private static Class<?> launchActivityClass;
    // 对应re-sign.jar生成出来的信息框里的两个值
    private static String mainActiviy = "com.xiaomi.channel.ui.ChannelLauncherActivity";
    private static String packageName = "com.xiaomi.channel";

    static {
        try {
            Log.v("LoginTest","start============");
            launchActivityClass = Class.forName(mainActiviy);
            Log.v("LoginTest","end============");
        } catch (ClassNotFoundException e) {
            System.out.println(e.getMessage());
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

    @SuppressWarnings("unchecked")
    public LoginTest() {
        super(launchActivityClass);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        Log.v("LoginTest","setUp============");
        this.activity = this.getActivity();
        this.solo = new Solo(getInstrumentation());
    }

    //米聊登陆 正确的用户名和密码
    public void testLoginWithIncorrentUsernameAndPassword(){
//      //一定时间以内等待text出现，否则出错 单位 毫秒
        solo.waitForText("Log In", 1, 10000);
//      点击text “Log In”
        solo.clickOnText("Log In");
        //一定时间以内等待text出现，否则出错 单位
        solo.waitForText("OK",1,2000);
        //输入text
        solo.enterText(0, "1234555");
        solo.enterText(1, "123");
        solo.clickOnText("OK");

        solo.waitForText("Incorrect ID number or password.", 1, 10000);
        assertTrue(solo.searchText("Incorrect ID number or password.", true));
    }   

    @Override
    protected void tearDown() throws Exception {
            this.solo.finishOpenedActivities();
    }

5、执行测试，console 端报错如下：

7、在真机上测试都 ok,在模拟器上就 crash，下载了微信 apk 测试后也是同样情况；被测程序有源代码也能正常跑。
8、由于本人比较固执，想弄明白为什么在模拟器上会 crash，不想不了了之。
8、出问题后在网上搜了各种解决办法都不行，恳请大家帮忙分析分析，万分感谢！！
