View 2 Replies View RelatedI want to rename an context private file created with openFileOutput() but I don't know how...
I tried that:
CODE:..................
This code throw FileNotFoundException but the documentation said "Open a private file associated with this Context's application package for writing. Creates the file if it doesn't already exist." so the new file should be created on disk.
The problem: When I try to read from the new renamed file I got FileNotFoundException!
These days I am working on a project that I need to modify some other android apk's arm elf .so file.Because I changed the code namespace in android Java, so I have to change the corresponding native code's namespace in .so file.
For example change the symbol Java_com_example1_Method to Java_com_example2_method (dynamic symbol). But I don't have the source code of the native code.The change only replace 1 or 2 chars, so we don't need extra memory allocation.
I have been struggled for 3 days with no results. how to rename the dynamic symbols in elf .so file, and recaculate the .hash section.
Is there an app or camera widget that will set my taken photo names to include the date or my name or something similar?

View 3 Replies View RelatedI have a swf file on the sdcard and I wrote a html file flash.html with the swf file embeded. The only way to open it now is:
1) open the browser
2) type in file:///sdcard/flash.html The swf runs fine.
But if use the code list below:
Uri uri = Uri.parse("file:///sdcard/flash.html");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent); It shows the error: The application has stopped unexpectly.
I also tried the following code using:
WebView: WebView browser = (WebView) findViewById(R.id.list_web);
browser.loadUrl("file:///sdcard/flash.html");
The Webview showed up, but the area should start the swf is empty. So is there a way to open the html through code? I also think if there is a way to open the android browser using ACTION_VIEW by a simple html then reset the URL to be "file:///sdcard/ flash.html" through code?

View 1 Replies View RelatedI recently decided to try out making my app tentatively "GoogleTV ready" by ensuring a user can do everything without ever entering Touch mode. For most stuff it is pretty straight forward, but I'm scratching my head at MapView/ItemizedOverlay: The docs appear to indicate that onTap(index) should do the trick, but it seems not to work the way I expect it to. "onTap ... This could be from a touchscreen tap on an onscreen Item, or from a trackball click on a centered, selected Item..."
Working around it using onTrackballEvent() and perhaps an onFocusChangeListener seems possible, but the documentation appears to indicate that this should not be needed for simple cases, right? I get the circle in the center and can move around with the D-pad/trackball, but when trying to select, hitTest() is not called and onTap(index) appears to be called with stale info. Anyone got a working code snippet? (Mark's NooYawk sadly doesn't work and googling came up with blanks apart from questions without answers).
I am trying to integrate Google Health on android and am trying to use a client login example which is working fine as a standalone java program.

I am using the same code that was used in the example code provided by google for client login. Can someone let me know where I am going wrong or what I am missing..................
View 3 Replies View RelatedI'm writing an app for Android OS, and I need to store some time values in the SQLite DB. I have been using android.text.format.Time to store the time values in the app, and then inserting the values as millis into the DB as REAL values. On the SDK emulator, everything works perfectly. On the sole phone I've had the opportunity to test my app (so far), my duration code doesn't work as expected. Some relevant code:
private static final String DATABASE_CREATE =
"create table " + DATABASE_TABLE + " ("
+ KEY_ROWID + " integer primary key autoincrement, "
+ KEY_START + " REAL, "
+ KEY_STOP + " REAL, "
+ KEY_DUR + " REAL );";
private SQLiteDatabase mDb;
ContentValues timerValues = new ContentValues();
timerValues.put(KEY_START, stime.toMillis(false));
timerValues.put(KEY_STOP, etime.toMillis(false));
timerValues.put(KEY_DURATION, stime.toMillis(false)-etime.toMillis(false));
int result = mDb.insert(DATABASE_TABLE, null, timerValues);
I pull this data from two separate functions with slightly different bits of code, both using Time.set(long millis), both giving incorrect results: The start and stop values come back correct, but the duration comes out 17 hours too large. Am I missing something about calculating durations or does this just seem like there's something "special" about this particular droid? I'll have another droid to test on Monday, but any ideas are appreciated.

View 2 Replies View RelatedI'm trying to create a simple text based game in which I ask a question based on a movie. The list of movie's is in a text file which I've included in res/raw. So basically I want to have a default string, say "Who acted in", followed by the name of the movie. Could I have the first string (along with a submit button etc) in my res/layout/main.xml file, and follow that with the movies name, after I've extracted it from the text file in my activity, or does the layout have to be defined in one place only?
