问题 I want to make an application which has auto start option in its settings. I have made Settings activity in my application which is derived from PreferenceActivity and give CheckBoxPreference for auto start option.

问题 I'm looking for a way to open the Android gallery application from an intent. I do not want to return a picture, but rather just open the gallery to allow the user to use it as if they selected it from the launcher ( View pictures/folders ). I have tried to do the following: Intent intent = new Intent(); intent.setAction(android.content.Intent.ACTION_GET_CONTENT); intent.setType("image/*"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); However this is causing the

问题 I want to launch a new fragment to view some data. Currently, I have a main activity that has a bunch of actionbar tabs, each of which is a fragment. So, within a tab fragment, I have a button, chartsButton. I have my onclicklistener all set for it, and here's the onClick method: public OnClickListener chartsListener = new OnClickListener() { @Override public void onClick(View v) { Intent chartFragment = new Intent(); startActivity(chartFragment); } }; Now, as I said, this listener is within

问题 My app creates mails with attachments, and uses an intent with Intent.ACTION_SEND to launch a mail app. It works with all the mail apps I tested with, except for the new Gmail 5.0 (it works with Gmail 4.9), where the mail opens without attachment, showing the error: "Permission denied for the attachment".
