I have got several mp3 files added as raw resource to my project. I would like to play them with AudioPlayer. I had FileNotfoundException and I backtraced it to find that the files can be found but they are not readable:
mp1.stop();
mp1.reset();
playedSound = R.raw.sip02;
String str = getResources().getString(playedSound);
File file = new File(str);
//((File)file).setReadable(true);
boolean readable = file.canRead(); //returns TRUE
file.setReadOnly();
readable = file.canRead(); //returns TRUE
FileInputStream inputStream = null;
try {
inputStream = new FileInputStream(file);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace(); //enters this branch
}
I cannot call file.setReadable() because I use API level 7.

I would like to get uses-permission using groovy.
Maybe like this,
def manifestXml = new XmlParser().parse(Manifest)
manifestXml."uses-permission".each { p ->
println p.attribute("android:name")
}
How to get attribute like android.permission.WRITE_EXTERNAL_STORAGE
You can use XmlSlurper
def manifestXml = new XmlSlurper().parse(Manifest)
manifestXml."uses-permission".each { p ->
println p."#android:name"
}
Use XmlSlurper get ActivityName
def manifest = new XmlSlurper().parse(xmlFilePath)
String pkg = manifest.#package
manifest.application.activity.each {
String actName = it.'#android:name'
if (actName.substring(0, 1).equals('.')) {
actName = pkg + actName
}
println(actName)
}

Have you tried removing the protocol from the URL, like so:
client.connect("ftpbrasnet.no-ip.org/");

Error in line Translate.setHttpReferrer("http://translate.google.com.vn/");
The method setHttpReferrer(String) is undefined for the type Translate
I am not sure if you are aware but Translate API is no longer free. so you would need to set the API key as well..
instead of using
Translate.setHttpReferrer("http://translate.google.com.vn/");
use
GoogleAPI.setHttpReferrer("http://translate.google.com.vn/");
GoogleAPI.setKey(/* Enter your API key here */);
This function is used to save image on sdcard (I have tested it on the emulator only):
public String SaveImage(String URL,String imagename){
Bitmap bitmap = null;
InputStream in = null;
String path = Environment.getExternalStorageDirectory().toString();
File dir = new File(path + "/bh");
if(!dir.exists())
new File(path + "/bh").mkdir();
Log.i("in save()", "after file");
File mImageFile = new File(path+"/bh/"+imagename);
if(mImageFile.exists())
Toast.makeText(mContext, "Saved", Toast.LENGTH_LONG).show();
try{
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
FileOutputStream out = new FileOutputStream(mImageFile);
bitmap.compress(CompressFormat.JPEG, 100,out);
out.flush();
out.close();
in.close();
return imagename+".jpg";
}catch(IOException ex){
Log.e("==== Error in saving image ====",ex.getMessage());
return "";
}
}
I have added the required permissions like below :

You also need to use the Internet permission since you're connecting to the internet.
<uses-permission android:name="android.permission.INTERNET" />
Does your emulator support SDCard ?
Have a look at this great answer, it might be the issue https://stackoverflow.com/a/11468278/1635817
I am trying to send an Intent from the onCreate in an Activity to start an IntentService. However the IntentService's onHandleIntent is never being received. I have tried changing around the Manifest with Intent-filters but nothing seems to be working. No exceptions are being thrown, but the IntentService is simply not called.
Here is the onCreate
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
db = new TwitterDB(this);
String[] columns = new String[1];
columns[0] = TwitterDB.TEXT;
tAdapter = new SimpleCursorAdapter(this, 0, null, columns, null, 0);
tweets = (ListView)findViewById(R.id.listtwitter);
tweets.setAdapter(tAdapter);
Intent intent = new Intent(this, SyncService.class);
intent.putExtra("action", SyncService.TWITTER_SYNC);
this.startService(intent);
}
Here is the creator and onHandleIntent of the IntentService class, I know it is not being called because logcat never shows "Retrieved intent". The constructor is not called either (There was a log call in there, but I removed it.
public SyncService(){
super("SyncService");
twitterURI = Uri.parse(TWITTER_URI);
Log.i("SyncService", "Constructed");
}
#Override
public void onHandleIntent(Intent i){
int action = i.getIntExtra("action", -1);
Log.i("SyncService", "Retrieved intent");
switch (action){
case TWITTER_SYNC:
try{
url = new URL(twitterString);
conn = (HttpURLConnection)url.openConnection();
syncTwitterDB();
conn.disconnect();
}catch(MalformedURLException e){
Log.w("SyncService", "Twitter URL is no longer valid.");
e.printStackTrace();
}catch(IOException e){
Log.w("SyncService", "Twitter connection could not be established.");
e.printStackTrace();
}
break;
default:;
// invalid request
}
}
And here is the Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service android:name="SyncService"/>
</activity>
</application>
</manifest>
Move your service declaration outside of the scope of the TwitterTwoActivity in the XML file, as I have done here:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="SyncService"/>
</application>
</manifest>
You need to define the path to the service in your manifest, simply putting the name is not sufficient.
Change
<service android:name="SyncService"/>
to
<service android:name=".SyncService"/>
if SyncService is in the root of your package, add respective folder before .SyncService if needed.
