如何使用我的Andr​​oid应用程序，以将照片发送给Instagram的？ [英] How to send a photo to Instagram using my Android app?

问题描述

我的应用程序拍照，我想在Instagram的分享。

My app take photos and I want to share in Instagram.

我的应用程序将图像保存在此目录中

My app save the image in this directory

File storagePath = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/tubagram");

现在我想要得到的最后一张照片我抽放利用这个code在Instagram的分享

Now I'm trying to get the last picture I taked to share in Instagram using this code

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/*");

final ContentResolver cr = getContentResolver();
final String[] p1 = new String[] {MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.DATE_TAKEN};
Cursor c1 = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1, null, null, p1[1] + " DESC");

if (c1.moveToFirst() ) {

    Log.i("Teste", "last picture (" + c1.getString(0) + ") taken on: " + new Date(c1.getLong(1)));
}

shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+Environment.getExternalStorageDirectory() + "/DCIM/Camera/tubagram/" + c1.getString(0)));
shareIntent.setPackage("com.instagram.android");

c1.close();

startActivity(shareIntent);

我收到此错误消息无法下载文件举杯。 这面包是由Instagram的发送。

I receive a Toast with this error message "Unable to download file". This Toast is sent by Instagram.

我试图用这个链接的例子 - 分享Instagram的的照片 - 但没有工作。

推荐答案

我解决我的问题。

我的camera.takePicture后添加此行。

I add this line after the camera.takePicture.

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory())));

这行做了一个刷新和手机后，认识到保存在手机中的新闻图片。

This line do a "refresh" and after the phone recognize the news photos saved in your phone.

和我做对我的方法的一些变化

And I made some changes on my method

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/*");                 

final ContentResolver cr = getContentResolver();
final String[] p1 = new String[] {
    MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.TITLE, MediaStore.Images.ImageColumns.DATE_TAKEN
};
Cursor c1 = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1, null, null, p1[1] + " DESC");

if (c1.moveToFirst() ) {
    Log.i("Teste", "last picture (" + c1.getString(1) + ") taken on: " + new Date(c1.getLong(2)));
}

Log.i("Caminho download imagem", "file://"+Environment.getExternalStorageDirectory()+ "/Tubagram/"  + c1.getString(1) + ".png");

shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+Environment.getExternalStorageDirectory()+ "/Tubagram/" + c1.getString(1)+".png"));
shareIntent.setPackage("com.instagram.android");

c1.close();

startActivity(shareIntent);

和这个另一种方法我验证是否安装在手机上的Instagram的

And with this another method I verify if the Instagram is installed on the phone

private boolean verificaInstagram(){
    boolean installed = false;

    try {
        ApplicationInfo info = getPackageManager().getApplicationInfo("com.instagram.android", 0);
        installed = true;
    } catch (NameNotFoundException e) {
        installed = false;
    }
        return installed;
    }
