获取前台应用程序图标转换为base64
|
我正在尝试获取前台应用程序图标并将其转换为base64。我可以获取前台应用程序的名称，但是无法获取图标。编码时，我得到一个字符串，但不是图标。我不确定我的错误在哪里。这是我的代码
public class RunningServices {
private static Context context;
private static String ACTIVITY_SERVICE = \"activity\";
public RunningServices(Context myContext){
context = myContext;
}
public static RunningAppProcessInfo getRunningServices(){
RunningAppProcessInfo result = null, info = null;
String currentApplication;
ActivityManager am = (ActivityManager)context.getSystemService(ACTIVITY_SERVICE);
Drawable icon = null;
PackageManager pm = context.getPackageManager();
List <RunningAppProcessInfo> l = am.getRunningAppProcesses();
Iterator <RunningAppProcessInfo> i = l.iterator();
while(i.hasNext()){
info = i.next();
if(info.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND){
try {
CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
currentApplication= c.toString();
icon = pm.getApplicationIcon(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
System.out.println(currentApplication);
System.out.println(icon);
} catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
}
}
encodeIcon(icon);
return result;
}
public static void encodeIcon(Drawable icon){
String appIcon64 = new String();
Drawable ic = icon;
if(ic !=null){
Bitmap bitmap = ((BitmapDrawable)ic).getBitmap();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
// bitmap.compress(CompressFormat.PNG, 0, outputStream);
byte[] bitmapByte = outputStream.toByteArray();
bitmapByte = Base64.encode(bitmapByte,Base64.DEFAULT);
System.out.println(bitmapByte);
}
}
}

public static void encodeIcon(Drawable icon){ String appIcon64 = new String(); Drawable ic = icon; if(ic !=null){ ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); // bitmap.compress(CompressFormat.PNG, 0, outputStream); BitmapDrawable bitDw = ((BitmapDrawable) ic); Bitmap bitmap = bitDw.getBitmap(); ByteArrayOutputStream stream = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); byte[] bitmapByte = stream.toByteArray(); bitmapByte = Base64.encode(bitmapByte,Base64.DEFAULT); System.out.println(\"..length of image...\"+bitmapByte.length); } }
