我的应用程序拍照,我想在Instagram上分享.
我的应用将图像保存在此目录中
File storagePath = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/tubagram");
现在,我正试图通过这段代码获取我在Instagram上分享的最后一张照片
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,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);
我收到一个Toast,显示此错误消息“无法下载文件”.
这个Toast由Instagram发送.
我试图使用这个链接示例 – share a photo in instagram – 但没有用.
请帮帮我！！！
解决方法
我解决了我的问题.
我在camera.takePicture之后添加了这一行.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
此行进行“刷新”,手机识别出手机中保存的新闻照片.
我对我的方法做了一些改变
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[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);
通过另一种方法,我验证Instagram是否安装在手机上
private boolean verificaInstagram(){
boolean installed = false;
try {
ApplicationInfo info = getPackageManager().getApplicationInfo("com.instagram.android",0);
installed = true;
} catch (NameNotFoundException e) {
installed = false;
}
return installed;
}
