“针对Android O的应用无法再在其清单中为隐式广播注册广播接收器。”
ACTION_VIEW是隐式广播。
根据上述声明，人们不能再注册清单中任何URI的广播接收器。此时侦听URI的唯一方法是应用程序是否已在运行？

ACTION_VIEW是隐式广播。
通常不是。 - (void)startDecodingAudio {
if (!_converterConfigured){
return;
}
while (true){
if ([self hasFramesToDecode]){
struct MyUserData userData = {1, (UInt32)_decoderBuffer[_currPosInDecoderBuf].length, _decoderBuffer[_currPosInDecoderBuf].bytes};
uint8_t *buffer = (uint8_t *)malloc(128 * sizeof(short int));
AudioBufferList decBuffer;
decBuffer.mNumberBuffers = 1;
decBuffer.mBuffers[0].mNumberChannels = 1;
decBuffer.mBuffers[0].mDataByteSize = 128 * sizeof(short int);
decBuffer.mBuffers[0].mData = buffer;
UInt32 numFrames = 128;
AudioStreamPacketDescription outPacketDescription;
memset(&outPacketDescription, 0, sizeof(AudioStreamPacketDescription));
outPacketDescription.mDataByteSize = 128;
outPacketDescription.mStartOffset = 0;
outPacketDescription.mVariableFramesInPacket = 0;
OSStatus status = AudioConverterFillComplexBuffer(_audioConverter,
inInputDataProc,
&userData,
&numFrames,
&decBuffer,
&outPacketDescription);
NSError *error = nil;
if (status == kNoMoreDataError) {
NSLog(@"%u bytes decoded", (unsigned int)decBuffer.mBuffers[0].mDataByteSize);
[_decodedData appendData:[NSData dataWithBytes:decBuffer.mBuffers[0].mData length:decBuffer.mBuffers[0].mDataByteSize]];
_currPosInDecoderBuf += 1;
} else {
error = [NSError errorWithDomain:NSOSStatusErrorDomain code:status userInfo:nil];
}
} else {
break;
}
}
}
用于启动活动，而不是广播ACTION_VIEW操作。
一个人不能再注册为清单中任何URI的广播接收器
广播接收器很少过滤Intent（即Uri中有<data>个元素。
