+ (NSString *) stringToHex:(NSString *)str{
NSInteger result = [str integerValue];
NSString *hexStr = (result)?@"":@"0";

while (result!=0) {
     NSInteger reminder = result % 16;

    if(reminder>=0 && reminder<=9){
        hexStr = [[NSString stringWithFormat:@"%ld",(long)reminder] stringByAppendingString:hexStr];
    }else if(reminder==10){
        hexStr = [@"A" stringByAppendingString:hexStr];
    }else if(reminder==11){
        hexStr = [@"B" stringByAppendingString:hexStr];
    }else if(reminder==12){
        hexStr = [@"C" stringByAppendingString:hexStr];
    }else if(reminder==13){
        hexStr = [@"D" stringByAppendingString:hexStr];
    }else if(reminder==14){
        hexStr = [@"E" stringByAppendingString:hexStr];
    }else{
        hexStr = [@"F" stringByAppendingString:hexStr];
    }

    result /=16;
}

return hexStr;

Answer 2

那是因为您在SourceLoadable课程中的Exoplayer版本中存在错误，您可以修改此更改此行：

private byte[] sampleData;

到

private byte[] sampleData = new byte[INITIAL_SAMPLE_SIZE];

或使用Exoplayer最新版本。
