Sending Intent with Bundle Using Console

Sending intent with bundle using console

According to the source code am has no way of accepting input data of the bundle type

Update:
In Android 7.0 the intent parameters parsing code has been moved from Am.java to Intent.java and support for more data types (like Array[] and ArrayList<> of basic types) has been added. Unfortunately there is still no support for the Bundle type extras in am command.

How to include a bundle extra when testing Android broadcasts?

In this post say it is impossible to put bundle extra through adb. You can write simple test application and send app invite intent what you want:

Intent intent = new Intent("com.android.vending.INSTALL_REFERRER");
intent.setPackage("your_package");
Bundle bundle = new Bundle();
bundle.putString("com.android.vending.INSTALL_REFERRER", "your_invite_id");
bundle.putString("com.google.android.gms.appinvite.DEEP_LINK", "your_deep_link");
intent.putExtra("com.google.android.gms.appinvite.REFERRAL_BUNDLE", bundle);
sendBroadcast(intent);

I have tested google app invite in this way, but before tried to sent intent through adb too.

How to send byte[] intent extra value from command line?

It seems that there is no option for byte array extra.

Details:

Do you really need to send intent by byte array? How about send it by "integer array extra", and cast it to byte?

Passing value from one activity to another using intent

Change

i.putExtra(mobileno1, mobileno1);

to

i.putExtra("mobileno1", mobileno1);

You must pass key value pair. You are passing mobileno1's value in key, too. So you can't retrieve it using key = "mobileno1"

To avoid null pointer use this:

if (getIntent().getStringExtra("mobileno1") != null) {
    edtnum.setText(getIntent().getStringExtra("mobileno1"));
}

Hope its clear :)

Edit:

If you want to execute some code like that, make sure you add the TextChangedListener before you call setText.

Example:

This code didn't work for me:

    setContentView(R.layout.activity_main);
    e = (EditText) findViewById(R.id.etext);
    e.setText(myString);
    e.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub
            System.out.println("on");
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub
            System.out.println("after");
        }
    });

But if I call setText later to adding textChangedListener, it work fine, and I am able to see sysouts in console.

    setContentView(R.layout.activity_main);
    e = (EditText) findViewById(R.id.etext);

    e.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub
            System.out.println("on");
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub
            System.out.println("after");
        }
    });
    e.setText(myString);

Hope it helps.

Is it possible to send HashMap as extra in adb shell am broadcast?

Unfortunately it is not possible using am (at the moment).

All command line options that can be parsed by am can be seen in its sources: https://github.com/android/platform_frameworks_base/blob/master/cmds/am/src/com/android/commands/am/Am.java.

You can try to build your own am with such functionality (if it's necessary enough).

send Arraylist by Intent

The first part to understand is that you pass information from Activity A to Activity B using an Intent object, inside which you can put "extras". The complete listing of what you can put inside an Intent is available here: https://developer.android.com/reference/android/content/Intent.html (see the various putExtra() methods, as well as the putFooExtra() methods below).

Since you are trying to pass an ArrayList<Song>, you have two options.

The first, and the best, is to use putParcelableArrayListExtra(). To use this, the Song class must implement the Parcelable interface. If you control the source code of Song, implementing Parcelable is relatively easy. Your code might look like this:

Intent intent = new Intent(ActivityA.this, ActivityB.class);
intent.putParcelableArrayListExtra("songs", songs);

The second is to use the version of putExtra() that accepts a Serializable object. You should only use this option when you do not control the source code of Song, and therefore cannot implement Parcelable. Your code might look like this:

Intent intent = new Intent(ActivityA.this, ActivityB.class);
intent.putSerializableExtra("songs", songs);

So that's how you put the data into the Intent in Activity A. How do you get the data out of the Intent in Activity B?

It depends on which option you selected above. If you chose the first, you will write something that looks like this:

List<Song> mySongs = getIntent().getParcelableArrayListExtra("songs");

If you chose the second, you will write something that looks like this:

List<Song> mySongs = (List<Song>) getIntent().getSerializableExtra("songs");

The advantage of the first technique is that it is faster (in terms of your app's performance for the user) and it takes up less space (in terms of the size of the data you're passing around).
