广播和接收额外的双打

我正试图在adb shell中广播一个额外的广告。在我的Android的BroadcastReceiver中,我订阅了广播并将附加内容从Bundle中删除。

我的麻烦在于双打。我假设广播可以包含一个双,因为Bundle类有一个getDouble方法,例如:

double percentComplete = bundle.getDouble("percent_complete");

但是,adb shell中的am broadcast命令似乎不支持双精度数,只支持浮点数。当我发送浮动时,Bundle.getDouble()方法抛出一个内部异常,记录在警告级别,表明它无法将Float强制转换为Double。

我可以发送双打,还是我被迫使用花车?

如上所述,以下是我所知道的指定额外内容的标志。

<INTENT> specifications include these flags and arguments:
    [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
    [-c <CATEGORY> [-c <CATEGORY>] ...]
    [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
    [--esn <EXTRA_KEY> ...]
    [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
    [--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
    [--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...]
    [--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE> ...]
    [--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...]
    [--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>]
    [--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    [--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    [--efa <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]

您可以使用URI格式向<INTENT>am broadcast提供am startservice

adb shell am broadcast "intent:#Intent;action=android.intent.action.YOUR_ACTION;d.percent_complete=99.999;end"

URI格式supports以下extra类型:

Bundle b = intent.mExtras;
if      (uri.startsWith("S.", i)) b.putString(key, value);
else if (uri.startsWith("B.", i)) b.putBoolean(key, Boolean.parseBoolean(value));
else if (uri.startsWith("b.", i)) b.putByte(key, Byte.parseByte(value));
else if (uri.startsWith("c.", i)) b.putChar(key, value.charAt(0));
else if (uri.startsWith("d.", i)) b.putDouble(key, Double.parseDouble(value));
else if (uri.startsWith("f.", i)) b.putFloat(key, Float.parseFloat(value));
else if (uri.startsWith("i.", i)) b.putInt(key, Integer.parseInt(value));
else if (uri.startsWith("l.", i)) b.putLong(key, Long.parseLong(value));
else if (uri.startsWith("s.", i)) b.putShort(key, Short.parseShort(value));
else throw new URISyntaxException(uri, "unknown EXTRA type", i);
