增加快捷方式和删除快捷方式:
private void addShortcut() { Intent shortcut = new Intent( "com.android.launcher.action.INSTALL_SHORTCUT"); // 快捷方式的名称 shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name)); shortcut.putExtra("duplicate", false); // 不允许重复创建 // 指定当前的Activity为快捷方式启动的对象 ComponentName comp = new ComponentName(this.getPackageName(), getClass().getName()); shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent( Intent.ACTION_MAIN).setComponent(comp)); // 快捷方式的图标 ShortcutIconResource iconRes = Intent.ShortcutIconResource.fromContext( this, R.drawable.icon); shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconRes); sendBroadcast(shortcut); } /** * 删除程序的快捷方式。 */ private void deleteShortcuts() { Intent shortcut = new Intent( "com.android.launcher.action.UNINSTALL_SHORTCUT"); // 快捷方式的名称 shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name)); // 指定当前的Activity为快捷方式启动的对象 ComponentName comp = new ComponentName(this.getPackageName(), getClass().getName()); shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent( Intent.ACTION_MAIN).setComponent(comp)); sendBroadcast(shortcut); }发邮件:
public boolean sendEmail(String to[], String subject, String body, String attachementFilePath) { final Intent emailIntent = new Intent( android.content.Intent.ACTION_SEND); emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, to); emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body); if (attachementFilePath != null) { Uri attachmentUri = null; try { File file = new File(attachementFilePath); if (file == null) { Log.d("[RC] Mail", "File error: " + attachementFilePath); } else if (!file.exists()) { Log.d("[RC] Mail", "File does not exist: " + attachementFilePath); } else if (!file.canRead()) { Log.d("[RC] Mail", "File can't be read: " + attachementFilePath); } else if (!file.isFile()) { Log.d("[RC] Mail", "Invalid file: " + attachementFilePath); } else { attachmentUri = Uri.fromFile(file); Log.d("[RC] Mail", "Attachement path[size=" + file.length() + "]: " + attachementFilePath); Log.d("[RC] Mail", "Attachement URI: " + attachmentUri.toString()); } } catch (java.lang.Throwable ex) { Log.e("[RC] Mail", "Error: " + ex.toString()); } if (attachmentUri != null) { emailIntent.putExtra(Intent.EXTRA_STREAM, attachmentUri); } } emailIntent.setType(PLAIN_TEXT); List<ResolveInfo> availableSoft = (List<ResolveInfo>) mContext .getPackageManager().queryIntentActivities(emailIntent, PackageManager.MATCH_DEFAULT_ONLY); if (availableSoft.size() <= 0) { return false; } mContext.startActivity(Intent.createChooser(emailIntent, mContext .getResources().getString(R.string.menu_sendEmail))); return true; }默认使用Google chrome打开WebView:
//new Intent(Intent.ACTION_VIEW, uri) public void startActiviyByChromeIfExists(Context context, Intent intent) { try { Log.d("startActiviyByChromeIfExists", "Intent Scheme: " + intent.getScheme()); } catch (Exception e) { } if (context != null && intent != null) { intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); List<ResolveInfo> availableSoft = (List<ResolveInfo>) context .getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); for (ResolveInfo info : availableSoft) { if ("com.android.chrome".equals(info.activityInfo.packageName)) { intent.setComponent(new ComponentName( info.activityInfo.packageName, info.activityInfo.name)); context.startActivity(intent); return; } } if (availableSoft.size() == 0) { try { Toast.makeText(mContext, R.string.setting_no_browser_installed, Toast.LENGTH_LONG).show(); } catch (Exception e) { Log.e("startActiviyByChromeIfExists", e.getMessage()); } } else { context.startActivity(intent); } } }
