Sending intent to BroadcastReceiver from adb

问题

I've got BroadcastReceiver class:

public class IntentReceiver extends BroadcastReceiver {

    final String tag = "Intent Intercepter";

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            String data = intent.getStringExtra("sms_body");
            Log.i(tag, data);
            Toast.makeText(context, data.subSequence(0, data.length()), Toast.LENGTH_LONG).show();
        } catch (Exception e) {
            Toast.makeText(context, "Intercepted", Toast.LENGTH_LONG).show();
        }
    }
}

And also in manifest:

<receiver android:name="com.whereismywifeserver.IntentReceiver" android:enabled="true">
    <intent-filter android:priority="999">
        <action android:name="com.whereismywifeserver.intent.TEST"/>
    </intent-filter>
</receiver>

But when I try to send intent from adb, I receive error:

C:\Users\i.yesilevsky>adb shell am start -a com.whereismywifeserver.intent.TEST
--es sms_body "test from adb" -c android.intent.category.HOME -n  com.whereismywifeserver/.IntentReceiver
Starting: Intent { act=com.whereismywifeserver.intent.TEST t=[android.intent.category.HOME] cmp=com.whereismywifeserver/.IntentReceiver (has extras) }
Error type 3
Error: Activity class {com.whereismywifeserver/com.whereismywifeser
ver.IntentReceiver} does not exist.

When I create intent in code, everything works fine. So how can I send intent from adb?

回答1:

You need not specify receiver. You can use adb instead.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST 
--es sms_body "test from adb"

For more arguments such as integer extras, see the documentation.

I've found that the command was wrong, correct command contains "broadcast" instead of "start":

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test from adb" -n com.whereismywifeserver/.IntentReceiver

回答3:

The true way to send a broadcast from ADB command is :

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test from adb"

And, -a means ACTION, --es means to send a String extra.

PS. There are other data type you can send by specifying different params like:

[-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
[--esn <EXTRA_KEY> ...]
[--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
[--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
[--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...]
[--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE> ...]
[--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...]
[--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>]
[--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    (mutiple extras passed as Integer[])
[--eial <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    (mutiple extras passed as List<Integer>)
[--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    (mutiple extras passed as Long[])
[--elal <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    (mutiple extras passed as List<Long>)
[--efa <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]
    (mutiple extras passed as Float[])
[--efal <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]
    (mutiple extras passed as List<Float>)
[--esa <EXTRA_KEY> <EXTRA_STRING_VALUE>[,<EXTRA_STRING_VALUE...]]
    (mutiple extras passed as String[]; to embed a comma into a string,
     escape it using "\,")
[--esal <EXTRA_KEY> <EXTRA_STRING_VALUE>[,<EXTRA_STRING_VALUE...]]
    (mutiple extras passed as List<String>; to embed a comma into a string,
     escape it using "\,")
[-f <FLAG>]

For example, you can send an int value by:

--ei int_key 0

Another thing to keep in mind: Android 8 limits the receivers that can be registered via manifest (e.g., statically)

https://developer.android.com/guide/components/broadcast-exceptions

回答5:

As many already noticed, the problem manifests itself only if the extra string contains whitespaces.

The root cause is that OP's host OS/shell (i.e. Windows/cmd.exe) mangles the entered command - the " characters get lost, --es sms_body "test from adb" becomes --es sms_body test from adb. Which results in sms_body string extra getting assigned the value of test and the rest of the string becoming <URI>|<PACKAGE>|<COMPONENT> specifier.

To avoid all that you could use:

adb shell "am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body 'test from adb' -n com.whereismywifeserver/.IntentReceiver"

or just start the interactive adb shell session first and run the am broadcast command from inside of it.

回答6:

I had the same problem and found out that you have to escape spaces in the extra:

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test\ from\ adb"

So instead of "test from adb" it should be "test\ from\ adb"

Noting down my situation here may be useful to somebody,

I have to send a custom intent with multiple intent extras to a broadcast receiver in Android P,

The details are,

Receiver name: com.hardian.testservice.TestBroadcastReceiver

Intent action = "com.hardian.testservice.ADD_DATA"

intent extras are,

1. "text"="test msg",
2. "source"= 1,

Run the following in command line.

adb shell "am broadcast -a com.hardian.testservice.ADD_DATA --es text 'test msg' --es source 1 -n com.hardian.testservice/.TestBroadcastReceiver"

Hope this helps.
