从命令行启动Android活动 [英] Start Android activity from command line with extra

问题描述

我创建了一个简单的活动，我想从命令行开始并从命令行传递一些值。

I created a simple activity that I want to start from command line and pass in some value from command line.

但是，如果我尝试这样做

However, if I try to do

adb shell am start com.example.mike.app/.SimpleActivity --es "Message" "hello!"

然后接收活动中的消息， intent.getExtras（）返回null。

and then receive the message in activity, intent.getExtras() returns null.

活动：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);

    Intent intent = getIntent();
    Bundle bundle = intent.getExtras();
    Log.d(LOGTAG, intent == null ? "Intent is null" : "Intent is not null");
    Log.d(LOGTAG, bundle == null ? "Bundle is null" : "Bundle is not null");
}

结果：

SimpleActivity(12345): Intent is not null
SimpleActivity(12345): Bundle is null

推荐答案

正确的命令应该是

adb shell am start -n com.example.mike.app/.SimpleActivity --es "Message" "hello!"

带有 -n ....
