[Gts]Fail-GtsTvTestCases#testLauncherChange

【问题描述】

Gts-7.0-R4新增测试项、失败项。
-m GtsTvTestCases -t com.google.android.tv.gts.LauncherChangeTest#testLauncherChange
02-29 13:03:11 I/ModuleListener: [1/1] com.google.android.tv.gts com.google.android.tv.gts.LauncherChangeTest#testLauncherChange fail:
java.lang.AssertionError: Android TV launcher doesn't resolve first, resolve stack:
ResolveInfo.ActivityInfo.packageName: com.eeee.dddd priority: 0
ResolveInfo.ActivityInfo.packageName: com.google.android.pseudolauncheractivity priority: 0
ResolveInfo.ActivityInfo.packageName: com.android.tv.settings priority: -1000

【问题结论】

最新结论，chip-mk认同是Google的问题，已申请Google waiver。

猜测Google测试用例的问题，需要同芯片厂商沟通确认。

【分析详细】###

1.反编译GtsTvTestCases.apk分析测试用例的逻辑，梳理如下：

@Test
    public void testLauncherChange() throws Exception {
        String str = TAG;
        Log.i(str, "testLauncherChange()");
        PackageManager pm = InstrumentationRegistry.getContext().getPackageManager();
        Intent intent = new Intent("android.intent.action.MAIN");
        intent.addCategory("android.intent.category.HOME");
        List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);//1.获取所有，上述intent（过滤能力）的package
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("testLauncherChange() : resolveInfos.size(): ");
        stringBuilder.append(resolveInfos.size());
        stringBuilder.append("


");
        Log.i(str, stringBuilder.toString());
        Assert.assertFalse("No launcher present", resolveInfos.isEmpty());
        stringBuilder = new StringBuilder();
        for (ResolveInfo r : resolveInfos) {
            String debug = new StringBuilder();
            debug.append("ResolveInfo.ActivityInfo.packageName: ");
            debug.append(r.activityInfo.packageName);
            debug.append("	 priority: ");
            debug.append(r.priority);
            debug = debug.toString();
            StringBuilder stringBuilder2 = new StringBuilder();
            stringBuilder2.append("
	");
            stringBuilder2.append(debug);
            stringBuilder.append(stringBuilder2.toString());
            Log.d(str, debug);
        }
        String packageName = ((ResolveInfo) resolveInfos.get(0)).activityInfo.packageName;
        int priority = ((ResolveInfo) resolveInfos.get(0)).priority;
        StringBuilder stringBuilder3 = new StringBuilder();
        stringBuilder3.append("packageName: >");
        stringBuilder3.append(packageName);
        stringBuilder3.append("<");
        Log.i(str, stringBuilder3.toString());
		//根据堆栈打印我们发现，EE的Launcher不满足最后一处priority=2，这个需要修改。
		//但是用例的第二处要求包名是"com.google.android."，这不合理。怀疑测试用例有问题。
        if (packageName.equals("com.google.android.pseudolauncheractivity") || !packageName.startsWith("com.google.android.") || priority != 2) {
            StringBuilder stringBuilder4 = new StringBuilder();
            stringBuilder4.append("Android TV launcher doesn't resolve first, resolve stack:");
            stringBuilder4.append(stringBuilder);
            Assert.fail(stringBuilder4.toString());//堆栈显示在此处89行断言
        }
    }
}
